I’ve been maintaining a library for my own SaaS that handles role-based access control (RBAC) on both the client and server side. It worked well, but I wanted to push its performance even further. Specifically, I was aiming for: Faster permission checks – Moving from linear scans to bit-level operations More efficient memory usage – From O(n) arrays to O(1) bitmaps Better performance overall, especially under heavy load Working with edge computing completely reshaped how I think about performance. Here are a few things that really stuck: Memory is limited – You have to cache smartly and keep your footprint small Data proximity matters – Optimize for fast, local lookups Predictability is key – Avoid operations that vary in execution time Permission Checks Now ~10x Faster Before: Looping…  ( 4 min )

🔗 GitHub Repository: tfmbot/hcxdupcap This Python-based script automates the full cycle of capturing WPA/WPA2 handshakes, extracting them, and optionally cracking them using hashcat. It's built for Wi-Fi security auditing and wraps around powerful existing tools. Capture WPA Handshakes Uses hcxdumptool to capture raw Wi-Fi traffic (.pcapng) from a selected wireless interface. Monitor .pcapng in Real Time A watchdog process monitors the output file for changes. When updated, it automatically runs hcxpcapngtool to extract WPA hashes. Parse and Log Handshakes Extracted hashes are: Saved to hash.hc22000 (for use with hashcat) Logged with SSID info to SsidHash.txt Duplicate hashes are skipped using a set of known hashes in memory. Check and Install Dependencies Automatically checks for required tools: hcxdumptool, hcxpcapngtool, hashcat. Installs missing ones using apt. Start Monitor Mode Automatically Stops NetworkManager and wpa_supplicant before capture. Restarts them safely after capture ends. Crack Captured WPA Hashes (Optional) Offers to crack captured handshakes using hashcat and the rockyou.txt wordlist. Attempts to find rockyou.txt or prompts to download it if not found. sudo python3 hcxdupcap.py -i wlan0 -w mycapture.pcapng Replace wlan0 with your Wi-Fi interface in monitor mode. Default output is capture.pcapng.

This is a submission for the World's Largest Hackathon Writing Challenge: Building with Bolt. I wanted a productivity tool that helps plan the day realistically — something focused, not overwhelming. Inspired by sprint planning, ToDo Today turns each day into a mission: prioritize, execute, and win. It’s built for clarity, not clutter. ToDo Today is a web-based productivity app that guides users through daily sprint planning, helps them focus with a timer, build habits, track long-term goals, and review progress over time. Clean and intuitive, it’s built for people who want to do more — without doing too much. The app is a full web experience built with React 18, TypeScript, and Tailwind CSS. I defined clear models for Tasks, Goals, Sprints, Habits, and Settings. Features include a planning wizard, task execution view, recurring task logic, offline support via localStorage, and custom user preferences — all managed with React Context and useReducer. Designing the 3-step planning wizard while keeping it flexible and intuitive was tough. Managing recurring task logic, state syncing across sprints, and keeping the UI delightful without bloat also took iteration. Micro-interactions took time but made a big difference. I built a full productivity system in one shot — from brain dump to focus mode, with sprints, habits, goals, stats, and a smooth UI. No filler. Just focused execution. Real productivity needs just enough structure to guide action, but not so much it becomes a chore. A system with goals, habits, and daily flow can be simple and powerful — especially with thoughtful UX. bolt https://todotoday-1prompt-demo.netlify.app  ( 3 min )

In 2017, I climbed Mt. Fuji in sneakers. This was not a deliberate choice to increase the challenge—it was the result of excellent research and poor judgment about what that research actually meant. Everything I'd read suggested that Mt. Fuji was the "cakewalk of mountain climbing." Physically, the hardest portions amounted to scrambling over some big boulders. Most of the climb was no more taxing than hiking or climbing stairs. Japanese folks in their eighties made the journey for spiritual reasons. There were huts along the way for rest, food, and water. Based on this research, I concluded that sneakers would be perfectly adequate. The ascent was everything I'd been promised. I experienced sights I'd never imagined—cities glowing through breaks in clouds from above, walking through path…  ( 7 min )

Fit matters. Timing matters. So does trust. In the UK especially, when someone tells their GP they’re struggling with anxiety or depression, the most common referral is for CBT.

Table of Contents Binding - Creating Variables In Imperative Languages: A Refillable Box In Elixir: A Sealed Box Type Inference Trailing Question Mark and Exclamation Mark Rebinding - Updating Variable Values Memory Management in Elixir References In Elixir, we can assign a name to store a value, similar to how variables work in other programming languages. However, the concept of "variables" in Elixir is fundamentally different from those in imperative languages like Python or JavaScript. What we actually do in Elixir is not storing a value in a mutable container, but associating a name with a specific value. This process is called binding. Let’s first look at how variables work in a language like Python: >>> monthly_salary = 5_000_000 >>> monthly_salary = 6_000_000 Here, we can …  ( 6 min )

Concurrency control in databases has two main modes for handling conflicts. Traditionally, these are labeled "pessimistic" and "optimistic," but those names can be misleading. Let’s define them by what actually happens from a user point of view: Wait-on-Conflict: the operation blocks until the conflict is resolved, typically waiting for a concurrent transaction to either commit or abort and release its locks. For most Online Transaction Processing (OLTP) workloads, this process is usually quick, unless a long-running transaction is blocking progress or there is a deadlock in which two transactions are waiting on each other. Fail-on-Conflict: Instead of waiting, the operation immediately raises an error to the application. Now it’s up to the application to decide: retry after a short pause …  ( 9 min )

As a junior frontend developer, navigating the ecosystem of modern web development can feel like entering a labyrinth. When I started with Angular and React, I was overwhelmed—frameworks, state management, component hierarchies, performance optimizations, testing—it was a lot to take in.

If you're a music lover and a tech tinkerer, here's a fun weekend project—building a custom Spotify desk widget using a Raspberry Pi and a 2.7-inch Waveshare e-Paper display. The idea is simple: every time a new song plays on Spotify, your e-Paper display automatically updates with the track title, artist, and album cover. This is made possible using Home Assistant, Python, and a few smart triggers. Here’s how it works: Home Assistant detects a change in the media player (Spotify), then fires a webhook to your Raspberry Pi. The Pi runs a Python script that pulls song data from Home Assistant’s API, generates a custom image using the PIL library, and displays it on the e-Paper screen. You can also fetch other data like weather to make your widget even more informative. This setup combines smart home automation and coding creativity—perfect for DIY fans. Not only does it save time from constantly checking your app, but it also looks sleek on your desk!  ( 3 min )

If your team needs 4 meetings to align on 1 thing… More Zoom calls ≠ more clarity. In fact, the teams I’ve seen collaborate best are the ones that talk less but still move in sync. Because they’ve built systems for clarity that don’t rely on real-time nudges. Clear decision trails Shared context that lives outside people’s heads Async ways to flag blockers and trade-offs The rest? Just noise with a calendar invite.

Side projects often begin with energy, ideas, and late nights, but without structure, they eventually stall. The excitement wears off when momentum disappears, and you spend more time maintaining than building.  Growth only begins when your side project evolves into something that functions like a system. Turning your idea into a Software-as-a-Service (SaaS) product shifts the focus from doing everything manually to creating something repeatable. A reseller app is one of the clearest paths to scale if your audience needs tools to sell, track, or manage services. It gives your users a way to act, not just read or watch. Instead of relying on content, you are creating infrastructure.  That change in direction gives your project staying power without forcing you to increase your workload ever…  ( 5 min )

Smart contracts look simple. A few lines of Solidity, some fancy modifiers, a deploy button and you’re live. Except you’re not. Because what seems like a tiny bug in your code could become a $1M exploit. And once it’s on-chain, you can’t just patch it on Friday and ship a hotfix. So, if you’re about to audit your first smart contract or you think your test suite has your back - here’s what I wish someone told me earlier. 🔹 Don’t Trust the Modifiers Common mistake: Using multiple modifiers (onlyOwner, nonReentrant, etc.) and assuming they execute in a predictable order. Tip: Flatten your control logic when auditing. Don’t just look at the function signature, follow the full execution chain. 🔹 Overflows Are Mostly Gone - But Underflows Still Bite Case: A staking contract calculated user re…  ( 4 min )

GitHub Homepage: https://github.com/eastspire/hyperlane My fascination with real-time web applications began during a project where we needed to push live updates to thousands of connected clients simultaneously. Traditional polling approaches created excessive server load and poor user experience. My exploration of Server-Sent Events (SSE) led me to discover an implementation that revolutionizes real-time web communication. The breakthrough came when I realized that SSE provides a simpler, more efficient alternative to WebSockets for many real-time scenarios. Unlike WebSockets, SSE works seamlessly with existing HTTP infrastructure, requires no special protocols, and provides automatic reconnection capabilities. My research revealed a framework implementation that maximizes these advantag…  ( 7 min )

Stamp signatures are essential for authenticating documents, particularly for digitally processed Word documents such as DOCX files. They provide a clear and legally valid method for confirming the origin, endorsement, or status of a document. For Java developers creating document management applications or workflow automation tools, having an effective way to programmatically apply stamp signatures can be a significant benefit. In our recent article, we guide you on how to incorporate stamp signatures into DOCX files using the GroupDocs.Signature Cloud Java SDK. With just a few straightforward REST API calls, you can embed cloud-based document signing directly into your Java applications. This eliminates the reliance on large desktop applications or manual processes, enhancing the scalabi…  ( 4 min )

By Muhammed Shafin P (@hejhdiss) In modern cybersecurity, most antivirus products claim to offer complete protection. However, many fail to address one of the most critical areas: deep network-level vulnerability scanning. Rather than building limited internal scanners, integrating existing tools like Nmap can significantly enhance security coverage. This article presents one sample case using Nmap for internet/network-level detection, but similar concepts apply across other layers of security as well. Most antivirus software: focuses on file-based malware detection performs limited or superficial vulnerability checks offers basic network alerts without full detail does not scan all ports or detect service versions lacks OS fingerprinting and deep inspection This results in weak security c…  ( 4 min )

This is a submission for the World's Largest Hackathon Writing Challenge: Beyond the Code. Some projects are built with planning. Others are built with panic, pressure, and memes. NoChill.AI? Definitely the second one. I built NoChill.AI solo during WLH, right in the middle of semester exams. Between cram sessions and late‑night coding, I simply wanted to create something fun. The moment my chatbot fired its first roast—“Still up at 3 AM? Really?”—I knew I’d crafted more than code. I’d made an experience that shows up, even when real friends can’t. I demoed NoChill.AI at a Code for India community meetup. Watching a room full of devs and students burst into laughter as the bot roasted volunteers was surreal. That instant feedback—real human laughter—made every all‑nighter worth it. While I didn’t dive deep into Bolt’s feature set, the Bolt Discord kept me motivated. Seeing others’ creative builds reminded me that even wild ideas belong in the hackathon. Collaboration with yourself: Balancing exams and solo coding taught me to prioritize and adapt on the fly. Fun has value: Not every AI needs to be serious—sometimes amusement is its own impact. Personal payoff: Building for myself—rather than a client—rekindled my love for pure creativity. Code for India for the welcoming demo stage The Bolt Discord community for inspiration Everyone who volunteered to get roasted (and survived) NoChill.AI may never be VC‑backed, but it delivered real‑world laughs, genuine community moments, and the simple joy of building something just for fun. That’s NoChill.AI: Built under pressure. Launched with laughter.  ( 3 min )

MindFLTR: Building a Therapy Match Tool with Bolt (My First Full-Stack Build to Deployment Project) When I joined the World's Largest Hackathon, I had a simple idea: create something that helps people explore therapy in a way that feels straightforward, accessible and informed. I wanted to test an idea I’d been sitting on, something to help people understand what kind of therapy might suit them best, because therapy is not a one-size-fits-all. That idea became MindFLTR — a short quiz that gives users a sense of which types of therapy might suit them best, based on how they think, feel, and approach various scenarios in life.

Have you ever needed to scrape data from websites? maybe for a side project, research, or just to automate some boring task? If you have, you probably know the pain: setting up scraping frameworks, writing code, dealing with endless configuration, and the wrestling against the messy unstructured data you get back. It's enough to make anyone want to throw their computer out the window. Literally me throwing my laptop on my employer’s face if MCPs weren’t there!! That's when you might have searched for tools like Firecrawl. If you haven't heard of it, Firecrawl is a tool that turns websites into structured, LLM-ready data with just a simple crawl. No more fighting with HTML parsing or weird edge cases - just write a prompt and let it do the work. But what if you could take it a step further…  ( 6 min )

After spending years building systems that demand true encapsulation and security boundaries, I’ve witnessed countless debates about privacy mechanisms in JavaScript. The introduction of JavaScript private elements (MDN) marked a fundamental shift in how we think about encapsulation in the language. While TypeScript’s private modifiers have served us well as training wheels, it’s time to acknowledge that JavaScript’s native private elements represent the superior approach for building robust, secure applications at scale. TypeScript’s private modifiers operate purely at compile-time. They’re suggestions, not enforcements. Once your TypeScript compiles to JavaScript, those private modifiers vanish like morning mist. Any developer with access to your runtime code can reach into your objects …  ( 7 min )

I've officially purchased a domain to launch my app: http://ghostlayer.io.vn/ This app helps humanize text so it won't be flagged as AI-generated. In other words, it transforms AI-generated content into natural, human-like writing while preserving meaning and intent. Beyond those who frequently use AI to write content, there are people who write their own content but still get incorrectly flagged by AI detection tools. This happens because they've learned writing styles from standardized tests like IELTS and TOEFL—the same sources these AI systems were trained on—leading to false positives. My app helps prevent these situations. When you search for it on Google right now, this app hasn't been indexed yet and won't show up in results since it typically takes several weeks or even months to get indexed and appear in search results, so just bookmark it first. Hopefully, one day many people will use this app. Even if it won't go viral, it'll serve as valuable experience for my other apps. I'll post a demo video later showing how it works.  ( 3 min )

LocallyTools has been live for a while now. Although the product uses browser capabilities to process data locally, users kept questioning its credibility—"Are you sure my files won't be uploaded?" "How can I prove that data won't leak?" These concerns pushed me to implement complete offline functionality. The idea was simple: if the app works perfectly when disconnected from the internet, that's definitive proof that data never leaves the user's device. During implementation, I discovered the benefits went far beyond my expectations: Building User Trust: When the product works offline, it directly proves data security. Users no longer need to "trust" my promises—they can verify it themselves. Reducing Server Load: With resources cached locally, most requests hit the local cache instead of…  ( 8 min )

Moonshot AI (a Chinese Artificial Intelligence company) recently announced their new AI model, Kimi K2, which is an open-source model purposely built for agentic tasks, and some even consider this model an alternative and open-source version of the Claude Sonnet 4 model. While Claude Sonnet 4 comes with $3/M input token and $15/M output token, Kimi K2 is a fraction of that and comes at $0.15/M input token and $2.50/M output token. Crazy, right? According to the Moonshot AI team, Kimi K2 has outperformed almost all coding models in many benchmarks, but of course, the main test comes with using and testing in a real-world scenario. So, in this article, we'll see what Kimi K2 can do and how well it compares with Sonnet 4 in coding. If you want to dive straight into the results and see how b…  ( 8 min )

One of the improvements of the AutoUpgrade tool in version 21c is the automation of certain steps involved in upgrading a RAC database. In versions prior to Oracle 21c, the following steps had to be performed manually to upgrade a RAC database: - Set the CLUSTER_DATABASE parameter to FALSE. - Stop all instances in the cluster. - Start one of the instances to begin the upgrade process. - Reset the CLUSTER_DATABASE parameter to TRUE after the upgrade is complete. - Start all instances. - Register the new version in the cluster. In version 21c, these steps are automatically handled by the AutoUpgrade tool (this feature was later backported to Oracle version 19.8 and above as well). The method for upgrading a database to version 21c using the AutoUpgrade tool has already been explained previously, so we will not repeat it here. We will only emphasize that before starting the upgrade process, all instances must be in the open state. 2022-02-05 09:59:40.024 INFO Updating parameter *.cluster_database=’true’ to *.cluster_database=’FALSE’ in /home/oracle/AutoUP_TO_21c/inst1/temp/during_upgrade_pfile_inst1.ora  ( 3 min )

It's no longer just about back-office accounting; ERP systems are becoming the nervous systems of modern enterprises. As businesses grow, so do their tech stacks. From CRMs to IoT platforms and cloud-native applications, companies often juggle a wide range of tools. Without a centralized system to streamline data flow and processes, information silos grow, productivity stalls, and decision-making suffers. That’s where ERP integrations step in. Modern ERP platforms are API-friendly, event-driven, and built to play well with DevOps pipelines and microservices. Here are a few real-world examples of how…  ( 4 min )

GitHub Homepage: https://github.com/eastspire/hyperlane My deep dive into resource management began during a production incident where our web server's memory usage spiraled out of control, eventually consuming all available system memory and crashing. Traditional garbage collection approaches couldn't keep up with our allocation rate, and manual memory management seemed too complex for a web application. This crisis led me to explore resource management strategies that could deliver both performance and reliability. The breakthrough insight came when I realized that effective resource management isn't just about memory allocation—it's about designing systems that use resources predictably and efficiently throughout their lifecycle. My research revealed a framework that implements sophisti…  ( 10 min )

We use snapshot testing at work quite heavily because it enables us to test the output of complex functions that do a lot of things at the same time and produce a lot of output. During a PR, I often accumulate a lot of files in one folder and when the PR is done, I want to clean up this folder, reset it to the state of the development branch, and re-create just the files I need. To reset a whole folder to the state of this folder on another branch in git, you can do: git restore --source=develop --staged --worktree tests/data This resets the tests/data folder to the state of that folder on the develop branch.  ( 3 min )

What are HTML forms? HTML forms are like digital paper forms, allowing users to input and submit data on websites. They are customizable and easy to maintain, making them a practical choice for online interactions. HTML forms are an essential part of interactive web design, enabling users to communicate with websites effectively. They have all the functionality of fillable PDF forms but are significantly easier to update and edit, providing you with a lot more control.

This makes them easy for use with screen readers. Furthermore, they are universally supported by modern web browsers and can be accessed on any device with an internet…  ( 4 min )

As a .NET developer, you’re likely eyeing OpenTelemetry (OTel) to bring observability to your applications—tracing, metrics, and logs, all in one. At Qumulus Cloud Platform , we’ve been integrating OTel into our .NET apps, and here’s what we’ve learned: Tunable Sampling: Dynamic or fixed sampling lets you control how much telemetry data is collected, balancing observability with performance. Async Efficiency: OTel plays nicely with .NET’s async/await, ensuring non-blocking operations when exporting telemetry. Real-World Testing: In our tests, CPU and memory overhead stayed under 2-5% for typical ASP.NET Core apps, but heavy tracing in high-throughput systems needs careful tuning. That said, it’s not plug-and-play. ❗Misconfigured exporters or excessive instrumentation can add latency. Our approach? Start small, profile rigorously, and leverage tools like Application Insights for seamless OTel integration. ✌ What’s your experience with OpenTelemetry in .NET? Have you noticed performance impacts, or found killer optimization tricks? Drop your insights below—let’s geek out on observability! 🧠  ( 3 min )

When you’re self-hosting a VPN, the software you choose isn't just about speed or security — it’s about how well it aligns with your setup, your goals, and your technical comfort zone. Two of the most widely trusted protocols are WireGuard and OpenVPN. Both are open-source, secure, and powerful. But under the hood, they take very different approaches. This blog breaks down how these protocols differ in design, setup, performance, and compatibility, so you can choose the right tool for your infrastructure.

Tkinter is python's de-factor standard GUI (Graphical User Interface) package. While it may not be as feature-rich as other libraries like PyQt or wxPython , its simplicity and ease of use make it an ideal choice for beginners. In this post, we'll focus on implementing ELSA, a chat application with a graphical user interface. ELSA (Emulated Learning and Speech Assistant) is a python-based chat application with a graphical user-interface (GUI) built using tkinter. It allows users to interact with a chatbot that can respond to predefined questions, provide current date and time, display images, and optionally convert text responses to speech using pyttsx3. Python 3.x Tkinter Pillow ( PIL ) pyttsx3 Type your messages in the entry field and press Enter or click Send. Use commands like hi, date, time, clear and bye for specific responses. Typing pic will display a random image from the img folder. Text-to-Speech - Click the Text to Speech button to toggle speech synthesis ON or OFF. Note: Speech synthesis requires speakers or headphones connected to hear the output. Clear Chat - Click Clear Chat to erase all messages from the chat window. The chatbot's responses are based on a predefined set of questions and answers stored in knowledge_base.json file. Implementing ELSA was a fun and interactive experience that taught me the basics of GUI programming with tkinter. Check it out here: https://github.com/vanu888/GUI-Bot.git  ( 3 min )

AI has become a buzzword in every business process imaginable. From automated customer support to generative content, it feels like every SaaS tool has slapped “AI” onto its feature list. But not all AI is created equal. The real disruption today is coming from something deeper — something far more capable than simple prompts or rules-based flows. It’s called Agentic AI. And it’s about to redefine how we think about automation. Agentic AI refers to artificial intelligence that can act autonomously, make independent decisions, and pursue goals over time — just like a human agent would. Where most traditional AI tools are reactive (e.g., answering a question or labeling an image), agentic systems are proactive. They can: Decide which task to perform next Chain multiple steps together Monit…  ( 6 min )

Identity is a fundamental layer of the internet—and it's broken. Current Web2 solutions rely on centralized gatekeepers, and most Web3 solutions lean heavily on public, immutable data. Neither is ideal for preserving user privacy or enabling nuanced, context-aware identity. Oasis Network is approaching this problem from a different angle: building confidential identity systems using trusted execution environments (TEEs) via the Sapphire runtime—its confidential EVM. The key idea is that identity doesn't have to be public to be verifiable. Developers can now build systems where: Users keep full control of their personal data Identity logic runs privately onchain Verification happens without exposing sensitive details This opens up new types of decentralized applications: Anonymous attestations (prove X without revealing Y) Privacy-preserving sybil resistance Zero-knowledge-style behavior without ZK complexity Reputation systems that evolve privately Oasis’s blog post breaks down the architecture and shows how privacy-preserving identity can be implemented entirely onchain, without sacrificing usability. If you're working on DAO governance, DePIN, or user-authenticated dApps, this is a model worth exploring. You can use familiar Solidity tooling, integrate with existing EVM workflows, and build more responsibly by default.  ( 3 min )

Hey devs! 👋 Welcome to my second weekly update on building Treazurex, a web application I’m building with React + Vite on the front-end and Node.js + PostgreSQL on the back-end. If you missed the first week’s post, this project is all about learning through doing, building out a full-stack shopping experience while picking up best practices along the way. At the start of the week, my plan was simple: Build the homepage and the shop page. But like many development journeys, I quickly realized that I had overlooked an important foundation, my back-end and database setup were still incomplete. Without a solid schema and working back-end logic, there was no way I could reliably fetch and display real product data on the front-end. So I shifted gears. Instead of pushing forward on the UI, I de…  ( 5 min )

This is a submission for Frontend Challenge: Office Edition sponsored by Axero, CSS Art: Office Culture. Ever stared at your screen for too long and thought, “What if my office desk was made entirely out of CSS?” No? Just me? Well… I did it anyway. I built a full-blown, interactive CSS art piece that captures the chaos, charm, and caffeine-fueled spirit of modern office life. From your keyboard lighting up as you type that email for the 7th time, to your favorite mug steaming with infinite coffee, it’s all here. Click Here for the Live Demo Let’s take a quick office tour: 💻 A monitor with endlessly scrolling code (because bugs never sleep) ⌨️ Keyboard keys that light up like a rave every time you hover ☕ Coffee mug steaming like it’s brewing life into your soul 🧊 Water cooler with animated convos (yes, tea is being spilled) 🪴 Plants that gently sway because HR said "Add greenery" 🏢 A window-lit building to remind you it's still Monday 📱 Fully responsive, so your office shrinks perfectly to mobile size! I started by sketching out the scene. Yes, on actual paper. Then came the fun part turning each element into CSS. I used: Gradients, borders, and pseudo-elements for juicy details Over 10 custom animations (because stillness is boring) Media queries to keep the art from falling apart on mobile How to make a cup of coffee.......with CSS That animating a keyboard can feel oddly satisfying You can make conversations happen at the water cooler, even in code Add draggable sticky notes (because who doesn’t like dragging stuff?) Make a day/night toggle so you can switch from burnout to blackout Maybe add sound effects? (Typing ASMR, anyone?) Built using 100% HTML and CSS (and just a sprinkle of JavaScript for those snazzy key animations). MIT licensed, so feel free to fork, remix, and add your own coffee mug 😄 Let me know what you think or what I should add next!  ( 4 min )

We have VictoriaMetrics and VictoriaLogs running on an AWS Elastic Kubernetes Service cluster. We do major upgrades to EKS by creating a new cluster, and therefore, we have to transfer monitoring data from the old VMSingle instance to the new one. For VictoriaMetrics, there is the vmctl tool which can migrate data through the APIs of the old and new instances, acting as a proxy between the two instances. With VictoriaLogs, the situation is still a bit more complicated and there are currently two options — let’s look at them further. So, here’s our setup: old Kubernetes cluster EKS 1.30 new Kubernetes cluster EKS 1.33 VictoriaMetrics and VictoriaLogs are deployed with our own Helm-chart which installs victoria-metrics-k8s-stack and victoria-logs-single through dependencies, plus a set of va…  ( 14 min )

Lately, there’s a growing debate over whether AI will completely replace Robotic Process Automation (RPA). Some predict RPA’s imminent demise. But is this prediction realistic? Here’s how we see it at Maybe: Automation today comes in two main flavors: Traditional RPA: Handles programmable, repetitive tasks. It’s predictable, stable, and efficiency-focused, like a factory assembly line. AI Agent: Manages vague but describable goals. It’s flexible and adaptive—more like a personal assistant. In short, RPA optimizes known tasks, while Agents handle unknown situations. Technical feasibility shouldn’t overshadow cost: RPA has a high initial setup cost but minimal ongoing expenses. After the upfront investment, it runs nearly for free. Agents, however, require continuous interaction with Large L…  ( 4 min )

This tutorial was originally published on IBM Developer. Large language models (LLMs) have transformed how developers build applications, but they face a fundamental limitation: they operate in isolation from the data and tools that make applications truly useful. Whether it's accessing your company's database, reading files from your filesystem, or connecting to APIs, LLMs need a standardized way to interact with external systems. The Model Context Protocol (MCP) addresses these limitations by providing a standardization layer for AI agents to be context-aware while integrating with the data and tools. Learn more about what MCP is, its client-server architecture components, and its real-world benefits in this “What is MCP?” article or in the MCP docs. The following figure shows the typical MCP architecture, with MCP hosts, MCP clients, MCP servers, and your own data and tools. In this comprehensive tutorial, we'll explore MCP and learn how to build a production-ready integration with IBM watsonx.ai, demonstrating how to create AI applications that can seamlessly connect to enterprise data and services.

If you’ve followed our last post on Deploying Your First Smart Contract Using KID, you probably deployed your first contract without touching a single CLI or RPC node. That’s a big step, but now comes the question: How do you interact with that contract from your frontend or backend app? In traditional development, this would be the part where you spin up an Express server or create API routes for your app. But in Web3, it usually means diving into ABI encoding, JSON-RPC specs, node configs, and all kinds of backend glue. That’s exactly what Kalp Studio’s API Gateway was designed to eliminate. In this article, we’ll walk you through how to go from a deployed smart contract to production-ready REST APIs, all within Kalp Studio.

GitHub Homepage: https://github.com/eastspire/hyperlane During my final year project on distributed systems, I encountered a fundamental challenge that shapes modern web development: how to enable efficient bidirectional communication between clients and servers. Traditional request-response patterns felt inadequate for the interactive applications we were building. My exploration of bidirectional communication led me to discover patterns that revolutionize how we think about client-server interaction. The breakthrough came when I realized that most web applications still operate under outdated communication paradigms designed for static content delivery. Modern applications require dynamic, interactive communication patterns that traditional HTTP cannot efficiently provide. My research re…  ( 8 min )

HEY FELLAS!! let’s take a real quick analogy to help us understand what an IP address and a MAC address actually are. So, imagine mailing a package across the country. IP address is like the full mailing address, It tells the system both where the package needs to go and where it’s coming from. In our analogy, your mailing address and your friend’s mailing address are the IP addresses of your device and your friend’s device. Here, It’s all about getting the data to the final destination, no matter how many networks (post offices in our analogy) it has to pass through. But along the way, You know, the package passes through several post offices (or we say routers in our networking world) , and at each one, it needs to be handed off to the right delivery person and that’s where the MAC address comes in. A MAC address is like a name tag stuck on your device’s network card. It’s unique to each device and helps deliver data within the same local network (In our analogy it could be several post offices) , you know like from one (post office) device to the next (post office) , one step (or “hop”) at a time. So it handles the hop-to-hop delivery from one stop to the next until it reaches the final destination.(To your friend in LA) Bottom line, when a message is being sent, the IP address helps guide it across the whole internet to reach it’s final destination, and at each step, the MAC address makes sure it reaches the right machine within that specific network.  ( 4 min )

When building a PC, memory modules (RAM) are rarely considered a “heat issue.” Unlike the blazing-hot GPU and CPU, RAM always seems to stay “cool and calm.” But did you know that as RAM frequencies climb and RGB lighting becomes more dazzling, heat management for DDR memory is becoming increasingly important? Let’s dive into why DDR memory heats up and how it cools itself down. Why Does DDR Memory Heat Up? Operational Current: Faster data transfer rates mean higher switching frequencies in the chips, resulting in more electrical current—and more heat. Power Management IC (PMIC): Starting with DDR5, voltage regulation moved from the motherboard to the RAM itself, adding extra heat directly to the module. RGB Lighting: Those mesmerizing LEDs may look cool, but they each generate heat, especially at high brightness levels. What Happens If RAM Gets Too Hot? The Unsung Hero: Heatsinks The Secrets of Heatsinks: Material: Most heatsink are made of aluminum for its excellent thermal conductivity and lightweight properties. High-end models may incorporate nickel-plated copper or even graphite. Design: Some feature fins or streamlined shapes to increase surface area for better heat dissipation. Active Cooling: Though rare, some extreme-performance RAM modules include mini fans for active cooling (e.g., ADATA XPG Spectrix). Heatsinks not only ensure stable performance but also add a sleek, professional look to your RAM modules—style meets function! RGB Lighting: Cool or “Too Hot to Handle”? RGB lighting has become a staple for modern RAM, capturing the hearts of PC enthusiasts. But those dazzling effects come at a thermal cost: Should Everyday Users Worry About RAM Temperatures? So, the next time you admire that RGB memory stick in your rig, take a moment to appreciate the cooling technology behind its glowing beauty. After all, behind every bright light is a hardworking, heat-handling "core" keeping things steady!  ( 5 min )

Step 1: Identify the Problem The first step in problem solving is recognizing and defining the problem clearly. This involves distinguishing between symptoms and actual root causes. For instance, declining employee performance might be a symptom, while the real problem could be poor communication or lack of training. Once identified, the problem needs to be analyzed in depth. This step involves gathering relevant data, reviewing past performance, and seeking insights from those affected. Analytical tools like the 5 Whys or Fishbone Diagram can help uncover underlying issues. Brainstorming is key during this stage. Teams or individuals should come up with multiple solutions without dismissing ideas prematurely. Creativity plays an important role, as innovative approaches often lead to the most effective results. Each potential solution is assessed based on factors such as cost, time, feasibility, and expected impact. This ensures that the chosen approach is both practical and effective. Once a solution is selected, it is put into action. This step involves planning, resource allocation, and clear communication to ensure smooth execution. After implementation, it’s crucial to monitor results and make necessary adjustments. Reviewing the outcome ensures the solution works as intended and prevents similar problems from recurring. Following these structured steps ensures a systematic approach to problem solving. It reduces the likelihood of errors, enhances efficiency, and leads to long-term positive outcomes.  ( 3 min )

Can you explain how the insert method works in this Java linked list implementation, and what role the head and tail pointers play in efficiently adding nodes to the list? The insert(int data) method creates a new node with the given integer value. If the list is empty (head == null), the new node becomes both the head and tail of the list. If the list already contains nodes, the new node is added to the end: The current tail node’s next pointer is updated to reference the new node. The tail pointer is then updated to point to the new node. package Interview_practice; class Node { public Node(int data) { this.data = data; } int data;// 0 Node next;// null } class link_list { Node head = null, tail = null; public void insert(int data) { Node n = new Node(data); n.next = null;// next null if (head == null) { head = n; tail = n; } else { tail.next = n; tail = n; } } public void display() { Node temp = head; while (temp != null) { System.out.print(temp.data + " "); temp = temp.next; } } } public class Linked_list { public static void main(String[] args) { link_list ls = new link_list(); ls.insert(10); ls.insert(101); ls.insert(102); ls.insert(104); ls.display(); } } Output:10 101 102 104  ( 3 min )

GitHub Homepage: https://github.com/eastspire/hyperlane My journey into real-time web communication began during a hackathon where our team needed to build a collaborative document editor. Traditional HTTP polling felt clunky and inefficient, leading me to explore WebSocket technology. What I discovered was a framework implementation that not only simplified WebSocket development but delivered performance characteristics that completely changed my understanding of real-time web applications. The breakthrough moment came when I realized that most WebSocket implementations add unnecessary complexity to what should be a straightforward communication protocol. My exploration revealed a framework that treats WebSocket as a natural extension of HTTP, enabling seamless real-time communication wit…  ( 8 min )

This is a submission for the World’s Largest Hackathon Writing Challenge: Beyond the Code. The most rewarding part of building Roots wasn’t the AI features, the DALL·E illustrations, or even the thousands of lines of code we shipped. It was the why — and the people we built it for. This hackathon gave us permission to dream big: what if we could replace a broken, bureaucratic school platform with something joyful, modern, and human? What if public school families — the ones often left behind — could access tools that felt like they were made just for them? ⸻ Our “Why” Was Personal I didn't grow up in Madrid.

GitHub Homepage: https://github.com/eastspire/hyperlane My fascination with asynchronous programming began during a project where our synchronous web server could barely handle 100 concurrent users. The blocking I/O operations created a bottleneck that no amount of hardware could solve. This experience drove me to explore asynchronous programming patterns that could transform our application's scalability and performance characteristics. The paradigm shift came when I realized that asynchronous programming isn't just about performance—it's about fundamentally rethinking how applications handle concurrent operations. My research revealed a framework that demonstrates how sophisticated async patterns can be both powerful and intuitive, enabling developers to build highly concurrent applicati…  ( 10 min )

Building modern web applications often means dealing with the naming convention mismatch between frontend and backend systems. Your React or Vue frontend might use camelCase (firstName, emailAddress), while your Laravel backend expects snake_case (first_name, email_address). This disconnect creates friction in development and requires manual transformation logic that clutters your codebase. Enter the Laravel Case Mapper Request package—a elegant solution that automatically transforms incoming request keys to match your validation expectations using PHP 8+ attributes. Modern frontend frameworks like React and Vue.js typically follow camelCase naming conventions: const userData = { firstName: "John", lastName: "Doe", emailAddress: "john@example.com", phoneNumber: "123-456-7890" } H…  ( 6 min )

So here's a quick story. I was working with this huge dataset — over a million records — and my code was crawling. I expected some lag, sure, but not this bad. So I decided to dig in and figure out what was going on. Each record in the dataset came from a different source, which meant the object structures were kind of all over the place: const records = [ { userId: 1, action: 'click', timestamp: 172383 }, { action: 'scroll', userId: 2, time: 172384 }, { id: 3, action: 'hover', timestamp: 172385 }, ]; At a glance, they look fine — just slightly different. But that slight difference? It was killing performance. After a bit of research and profiling, I realized the issue was tied to how the V8 engine (used in Chrome and Node.js) optimizes object access. It uses something called …  ( 4 min )

If you're just starting with Laravel, you've likely heard the term "migrations" — and you might be wondering: What are Laravel migrations and why should I care? This post will walk you through the basics, helping you confidently create and manage database schemas using Laravel’s migration system. Migrations are Laravel’s way of version-controlling your database schema using PHP code instead of raw SQL. Think of them like Git for your database tables: You can create, modify, and remove tables through migration files. You can share those changes with your team. You can track and rollback changes easily. They make your database predictable, portable, and team-friendly. Run the following Artisan command in your Laravel project: php artisan make:migration create_users_table This will generate …  ( 5 min )

GitHub Homepage: https://github.com/eastspire/hyperlane During my advanced systems programming course, I became obsessed with understanding how data moves through web servers. My professor challenged us to minimize memory allocations in HTTP request processing, leading me to discover zero-copy techniques that fundamentally changed my approach to web server optimization. This exploration revealed how eliminating unnecessary data copying can dramatically improve both performance and memory efficiency. The revelation came when I profiled a traditional web server and discovered that a single HTTP request often triggers dozens of memory allocations and data copies. Each copy operation consumes CPU cycles and memory bandwidth, creating bottlenecks that limit server performance. My research led m…  ( 7 min )

GitHub Homepage During my junior year studies, high concurrency processing has always been one of the technical fields I'm most interested in. While traditional multi-threading models can handle concurrent requests, they often encounter performance bottlenecks when facing large numbers of connections. Recently, I deeply studied a Rust-based web framework whose high concurrency processing capabilities gave me a completely new understanding of asynchronous programming. In my previous projects, I used thread pool-based concurrency processing models. This model allocates a thread for each request, and while implementation is simple, it has obvious scalability issues. // Traditional Java thread pool model @RestController public class TraditionalController { private final ExecutorService th…  ( 8 min )

Once I posted about my WebRTC SFU library. Developing a WebRTC SFU library in Rust I’ve recently added a recording function to this project. This update brings new capabilities for capturing and processing RTP streams in flexible, server-friendly manner. The v0.5.0 release introduces recording features. And I published the documentation site. The recording feature is explained on the site. https://h3poteto.github.io/rheomesh//pages/04_recording/ Rather than creating a monolithic function that handles everything from capture to file generation, I opted for a more modular approach. The recording functionality simply forwards raw RTP packets, leaving encoding and file creation to external tools like FFmpeg or GStreamer.

Beyond the Black Box: Why We Built Context Space as a Tool-First Infrastructure If you've built an AI agent recently, you've likely felt a strange mix of awe and frustration. On one hand, its capabilities are astounding. On the other, trying to debug why it chose one action over another feels like staring into a black box. The agent's reasoning is opaque, its behavior unpredictable, and scaling its abilities often leads to an exponential increase in chaos. At Context Space, we believe this isn't a fundamental flaw of AI, but a symptom of the current development paradigm. We're trying to build predictable systems on top of a non-deterministic black box. Our answer? A shift in perspective. We're building Tool-First. A Tool-First approach flips the script. Instead of treating the LLM as the…  ( 5 min )

Hello, Dev Community! I'm Quetzalquant — and today, I begin a personal and professional journey that merges data, storytelling, and purpose. For years, I’ve studied financial markets, data analysis, and narrative structures. Recently, I’m building my path as a data-driven storyteller focused on financial systems — both traditional and decentralized. In a world flooded with numbers, dashboards, and noise, the actual meaning of data often gets lost. Markets are reduced to tickers. Users are reduced to wallets. And financial decisions are made on shallow signals. But behind every chart, every token, every dataset — there’s a story. A need. A value being created (or destroyed). And I believe we must tell those stories with clarity, responsibility, and vision. I help fintech startups, DAOs, and individual traders: Translate their financial data into visual insights (Python, SQL, DuckDB) Convert complex reports into accessible, strategic content (white papers, institutional reports) Communicate their value in ethical, clear narratives — not hype, not smoke. This is not about selling a service. It’s about offering a lens: a way to make sense of systems that shape real lives. I'll be publishing here weekly, sharing: Technical articles (data visualization, financial analysis, Python tools) Strategic narratives (case studies, market behavior insights, trading analysis) Ethical reflections on Web3, open finance, and narrative design for impact If you believe stories matter in the age of data, we might be aligned. You can find more of my work on LinkedIn https://www.linkedin.com/in/quetzalquant/ , or follow my journey here as I build this freelance project from scratch — ethically, transparently, and with intention. This is not a startup built in Silicon Valley. This is a startup built with soul, signal, and story. Thanks for reading. More soon.  ( 3 min )

The problem with AI agents isn’t the model, it’s missing context (and we built the fix) When the concept of MCP (Model Context Protocol) first emerged, I felt a jolt of genuine excitement. This was it. This was the key that would let us unlock the true potential of LLMs, allowing them to interact with tools and the real world. I jumped in headfirst, my mind buzzing with ideas for truly intelligent agents. Then reality hit. My initial excitement quickly turned into a grinding frustration. The cycle became depressingly familiar: Spend hours figuring out the right API calls for a tool. Manually edit a sprawling, unforgiving config.yaml file. Worry constantly about accidentally committing secret keys. Finally get it to work, only to have the agent forget a crucial piece of information from t…  ( 4 min )

Jarvis from Iron Man isn't just science fiction—it's becoming a design goal. In this talk, Kent C. Dodds explores what building a "Jarvis-like" experience might look like using MCP, and what challenges still stand in the way. Creating a unified AI assistant that knows your context, acts across applications, and proactively helps is a daunting task. The biggest hurdles: Trust and privacy in delegating personal tasks. Seamless integration without user-managed servers. Multimodal communication (text, voice, UI). Proactive support and long-term memory. Today’s tooling—LLMs, UI frameworks, MCP—can enable these features, but they are fragmented.

Why I Analyzed UK Laptop Trade I run a laptop import business in India and recently began exploring the idea of expanding to the UK. Before making any strategic decisions, I wanted to understand the actual trade flow of laptops into and out of the UK. I used official data from the UN Comtrade Database and built an interactive Power BI dashboard to analyze seven years of UK laptop import and export activity (2019–2025). Here’s the interactive dashboard I built using Power BI: View the Live Power BI Dashboard Features include: Year, country, region, and trade flow filters KPIs showing total quantities and trade values Average unit price comparisons Import vs export trend charts Regional and partner country breakdowns The UK imports significantly more laptops than it exports. China is the dominant import partner by volume and value. UK laptop exports are relatively low, likely driven by re-exports or refurbished stock. Export unit prices tend to be higher, but quantities are much smaller. Seasonal spikes reflect broader tech consumption patterns. Source: UN Comtrade Database HS Code: 847130 (Portable laptops) Time Range: 2019–2025 Frequency: Monthly Access the cleaned and raw datasets on GitHub: GitHub Repo with Dataset and Notes Tools and Process Power BI for dashboard development Excel and Power Query for data cleaning and transformation GitHub for dataset storage and collaboration Based on the data, the UK's laptop trade is largely one-directional. The UK acts as a consumer hub, heavily reliant on imports, with limited outbound trade in laptops. This insight is particularly valuable for anyone interested in international tech supply chains, business expansion, or digital market trends. If you’re interested in similar visualizations or exploring trade data for other products or markets, let me know.

AI is transforming software engineering, but how much does it really speed up development? Big tech companies claim that AI can boost code output by 30% or more. But does that mean teams are actually 30% more efficient? Are features reaching customers 30% faster? Let's dig in and find out. With my knowledge of queue theory and the theory of constraints made me skeptical. Sure, developers might code faster with AI, but what about bottlenecks elsewhere in the pipeline? Could speeding up coding actually slow things down downstream? And what about tried-and-true practices like pair programming and trunk-based development, are they even faster than using pull requests and feature branches? I decided to put these ideas to the test with a simulation, using GitHub Copilot and some queue theory too…  ( 6 min )

In modern applications, different parts of a system often need to react to changes without being tightly coupled. For example, when a user registers or an order is placed, several components might need to send notifications, update analytics, or trigger workflows. The Domain Event Pattern provides a clean solution to this problem by modeling significant business events as immutable facts. It allows systems to communicate through events in a decoupled way, making them more modular, scalable, and easier to maintain. The Domain Event Pattern, a key concept in Domain-Driven Design (DDD), captures significant changes within your business domain as immutable events. A domain event represents a fact that has already occurred - such as "Order Created" or "User Registered" - and includes details li…  ( 6 min )

O padrão Observer Antes de abordarmos as signals no Django, vale entender o padrão de design que as inspira: o Observer. O padrão Observer, também conhecido como "publicador-assinante" (ou pub-sub), consiste em definir um mecanismo onde certos objetos (os observadores) reagem automaticamente a mudanças em outro objeto (o sujeito). Isso é útil quando você quer que partes diferentes do sistema fiquem "de olho" em algum evento e ajam quando ele ocorrer, sem precisar acoplar diretamente os componentes envolvidos. No contexto do Django, o sujeito geralmente é um model (por exemplo um User) e os observadores são funções que você registra para reagir a eventos como salvar ou deletar esse modelo. Sempre que um desses eventos acontece, todos os observadores registrados são notificados automaticam…  ( 6 min )

Create a secure, biometric access control system that unlocks a servo-powered latch when it detects an enrolled fingerprint. Perfect for geocache boxes, garage doors, or any physical access control application. A complete fingerprint authentication system using: R503 fingerprint sensor for biometric scanning and enrollment Servo motor controlling a physical latch mechanism Raspberry Pi 4 running the Viam robotics server Custom control logic that triggers the servo when fingerprints match Fingerprint Management: Enroll up to 200 different fingerprints across multiple slots, with support for enrolling the same finger multiple times to improve recognition reliability under varying angles and pressure. Automated Latch Control: Servo automatically moves to open position (180°) when authorized fingerprint detected, then returns to closed position (90°) after configurable timeout (default 30 seconds). Remote Configuration: Use Viam's web interface to test components, enroll new fingerprints via JSON commands, and monitor sensor readings in real-time. Extensible Design: Build mobile or web apps using Viam's SDKs to create user-friendly enrollment interfaces for others to add their fingerprints. Raspberry Pi 4 with USB flash drive R503 fingerprint sensor USB-to-serial adapter for sensor connectivity Servo motor (SG90 or similar) Jumper wires and connection materials Optional: 3D-printed or custom enclosure and latch mechanism The tutorial walks through complete setup including Raspberry Pi OS installation, SSH configuration, Viam platform setup, component wiring diagrams, and step-by-step fingerprint enrollment using JSON commands. The modular design separates sensor detection, servo control, and coordination logic for easy customization. Ready to build your own biometric lock?

Mounting Amazon EFS across multiple AWS regions is not something you do every day—but when you need to, the pain becomes real. In this article, I’ll walk through how I achieved cross-region EFS mounting from three AWS regions into a single Kubernetes (EKS) and EC2-based deployment. We’ll cover the architecture, common pitfalls, and practical work-arounds for both environments. EFS DNS is regional. Each mount helper expects the region-specific hostname (e.g., fs-1234.efs.us-east-1.amazonaws.com). When you point that hostname at a mount target in a different region, the helper often fails—especially inside Kubernetes—because it does a DNS check and won’t trust /etc/hosts overrides. Why Cross-Region EFS Mounting? We manage workloads that span multiple AWS regions to support high availability …  ( 4 min )

Overview This little project deals with very simple (2D) right body physics. I will not spoil all the fun - essentially we control a 2D rocket. It would be fun to visualize data processing in such a fashion on a node canvas - kind of matches our Divooka visual programming scheme. The hypothesis is that at least for 2-dimensional cruise control, a simple PID should be able to do something useful, and it's with that gut I am set to experiment a bit to verify my idea. I've done some experiments in July last year but ended up not going far due to technical challenges. The challenge was to get it working properly with physics setup. Per RigidBody2D doc: So is it relative or global? Without being able to visualize the force, it's a bit hard to tell also whether to use a force, or to use impulse. It's been a while and I almost gave up - never really have time to create our own physics engine. But Godot got a new physics kernel and I thought maybe give it a try. I've been doing some analytics and talking with ChatGPT on a new airship design that puts the air vessel at the bottom of the ship instead of hanging overhead - that inspired me maybe there are two things with current setup that's not working: After fixing a few API calls related to GraphEdit get_children() change. I was looking at the force application code once again: func _physics_process(delta): # Remark: We are not using to_global directly because of issues with viewport transform var left_anchor = %LeftThrusterCenterOfAction.position var right_anchor = %RightThrusterCenterOfAction.position # Remark: applied force is RELATIVE to the body (aka. current object) apply_force(Vector2(0, -1).rotated(rotation + _left_engine_angle_degrees / 180.0 * PI) * _left_engine_thrust, left_anchor) apply_force(Vector2(0, -1).rotated(rotation + _right_engine_angle_degrees / 180.0 * PI) * _right_engine_thrust, right_anchor) Again, it's really simple once we figure out what's the right way to do things.

I run my online income streams while bouncing between cities, hostels, and sometimes hammocks. Here's the AI stack that makes it possible — no coding required. Imagine this: you're in Vietnam. It’s 2AM. The Wi-Fi sucks. You’re on deadline. And you forgot to invoice your client in USD. That was me. After 6 months of chaos, I built a minimalist AI stack that now runs most of my content, scheduling, payments, and marketing — so I can focus on traveling, creating, and sleeping (sometimes). Fliki helps me turn my travel tips and blog posts into short-form videos with voiceover. Use case: Repurpose content into YouTube Shorts & TikToks — no editing needed. PromptimizeAI improves my prompts before I feed them to ChatGPT or Claude. Result: More accurate, SEO-friendly posts with less editing. Wise lets me receive client payments, pay in local currencies, and avoid huge conversion fees. Example: I saved over €250 in fees during 2024 just by switching. WayAway finds cheap flights and gives me cashback for every booking. Bonus: You can earn commissions if you promote it as an affiliate.

“I finally got ChatGPT to understand what I wanted!” When we work with AI, especially LLMs it can feel like there is a collaboration taking place. ChatGPT can retain basic facts between sessions, if memory is turned on. It might remember your name, your preferences, or the kind of projects you’re working on. And it “feels” like it is learning about you. Claude, by contrast, doesn’t remember anything once the conversation ends. Yet people still say things like, “Claude knows what I want,” or “I’ve trained Claude to respond the way I like,” as though it’s gradually evolving with them. This misunderstanding of AI’s capabilities isn’t just a quirky linguistic habit, it’s a risk. “It realized its mistake and tried to hide it.” When users believe AI understands them or learns over time, a few d…  ( 6 min )

If you’ve heard of ChatGPT, Bard, or Claude and wondered how these smart assistants work, you’ve come across something called an LLM, or Large Language Model. But what is an LLM really? Let’s break it down in the simplest way possible. 💡 What is a Large Language Model (LLM)? A Large Language Model is a type of computer program that has been trained to understand and generate human language. Think of it like a super advanced autocomplete on your phone—but way smarter. Imagine feeding a machine with billions of sentences from books, websites, and conversations, and then asking it to guess what comes next in a sentence. Over time, it gets really good at predicting and forming sentences that make sense, answer questions, or even write stories. 🧠 How Does It Work (In Simple Words)? Training: …  ( 4 min )

I want to share about my library for writing tests within transactions when working with MySQL. I enjoy writing tests for my code, but I dislike creating mocks and all the necessary boilerplate around them. This is especially true for databases - while mocking calls to external services and message queues isn't too difficult, databases present a much greater challenge. Interaction with databases is typically quite 'rich', which leads to having to write numerous fragile and tedious mocks/stubs. Moreover, the actual database queries themselves remain untested (and this is where errors often lurk, related to incorrect queries or schema migration mistakes). The solution here is to use a real database with test data that we populate before running all tests or a specific test. But this raises t…  ( 6 min )

Let’s be honest, if you’ve ever worked at a startup, you’ve heard it: “Can we ship this faster?” From the founder’s perspective, it’s all about momentum. From the developer’s side? It’s usually panic, duct tape, and a quiet prayer that no one notices the 600-line function you just pushed to production. So let’s talk about what “developer speed” really means and where it goes wrong. 1. Speed without direction = chaos You’ll move, but you'll probably break your nose (and your codebase) in the process. 2. Thinking short-term creates long-term pain What felt “fast” today becomes the bottleneck tomorrow. 3. Design and UX suffer when devs are rushed “Why aren’t users converting?” Spoiler: because no one thought about them. 4. Rewrites are way more expensive than getting it right 5. “It’s just code” is a dangerous mindset 👋 Final Thought And if you’re a dev stuck in the “just ship it” cycle: speak up. Speed means nothing if the product isn’t stable, usable, or scalable.  ( 4 min )

In the dynamic field of data science, interpreting data is fundamental to success. Whether predicting customer behavior, analyzing sales performance, or designing machine learning algorithms, understanding your data's characteristics is crucial. One of the primary tools for summarizing data is measures of central tendency. Measures of central tendency are statistical techniques used to determine the center or typical value of a dataset. They provide a single value that represents the entire distribution of data. The three main types are: The mean is calculated by summing all values and dividing by the number of values. It is the most commonly used measure and is particularly effective for normally distributed data. Mean = ∑x_i / n The median is the middle value when the data is arranged in…  ( 4 min )

I Built a Tool That Converts React + Vite to Next.js — Here’s Why (and How You Can Use It) Hey Devs I love working with React + Vite. It's fast, modern, and super developer-friendly. But every time I had to move a project to Next.js for SEO, SSR, or routing reasons… it was a mess. Manually migrating a React + Vite project to Next.js means: Replacing react-router with App Router or Pages Router Restructuring folders (/pages or /app) Managing "use client" everywhere Fixing hooks and providers Losing precious hours (and patience) So I built something to help. ViteToNext.AI A tool that automatically transforms your React + Vite project into a working Next.js App Router structure. Analyzes your routes, layouts, and components using AST parsing Converts React Router to app/-based routing Preserves your layouts and providers Adds "use client" where needed Lets you preview and export your Next.js-ready code (ZIP or GitHub) You can try it here: 👉 https://vitetonext.codebypaki.online Free plan for small projects (up to 10 routes) Agency plan for full migration and GitHub integration No login required to test basic features. Because developers shouldn’t have to waste time on tedious, error-prone rewrites. This tool started as a weekend project for myself… and it quickly became something useful for others. If it helps you save time, I’d love to hear it. Support for Pages Router Auto internationalization (next-i18next, next-intl) Provider detection and wrapping More layout heuristics If you’ve tried the tool — or you’ve done this migration manually before — I’d love to hear your story.

In this article, I'm going to explain what dependency injection is and how it solves a critical problem when building applications in Go. To make it concrete, I'll walk you through a problem I faced while building a backend for a tracker application using Test-Driven Development (TDD). The problem arose when I started writing my authentication services, specifically functions like GetUserByID and GetUserByEmail. To test my service logic, I wrote some initial tests using a mock database and a mock logger. However, I made a common mistake: I tightly coupled my UserService to those mocks. This meant that to move the application to production, I would have to go back and manually change the UserService and all its functions to use a real database and logger.

History of Linux How Linux Took Over the Tech World—In Simple Terms Early 1990s: A curious student named Linus Torvalds builds a small program (kernel) as a personal project. He shares it online, inviting others to join the ride. 1991: The first version of “Linux” is born. It's like the central engine (or heart) of a computer—but it needs other pieces to become fully usable. Mid-1990s to 2000s: Developers across the globe start adding the missing tools and features. Different versions, called "distributions" like Ubuntu, Fedora, and Red Hat—start popping up. 2000s: Linux becomes a go-to for powering servers. It later grows into mobile tech, forming the foundation for Android. Today: Linux is everywhere—in phones, laptops, smart devices, cloud infrastructure, supercomputers, and even spacecraft. Thanks to open collaboration, it keeps evolving. Basic Linux Commands Command Description ls List files and directories pwd Show current directory path cd [dir] Change directory mkdir [dir] Create new directory rmdir [dir] Remove empty directory rm [file] Delete file rm -r [dir] Delete directory and contents cp [src] [dest] Copy file or directory mv [src] [dest] Move/rename file or directory touch [file] Create empty file cat [file] View file content nano [file] Edit file using nano editor sudo apt install [pkg] Install package sudo apt remove [pkg] Remove package ✅ Why Use Linux?

Let’s get this straight: not all degrees are created equal. In 2025, the job market is brutal. Employers want more than just a certificate—they want proof you can solve problems, adapt quickly, and hit the ground running. That’s why choosing a career-focused degree is your smartest move if you’re planning to study abroad. But what makes a degree "career-focused"? And how do you know which one actually leads to jobs? Let’s break it down. A career-focused degree is a program that’s built to prepare you for real-world work. It’s not about theory alone. These degrees blend classroom knowledge with practical skills, internships, and clear pathways into the industry. Think of it like this: A typical academic degree = Knowledge A career-focused degree = Knowledge + Skills + Opportunity Examples i…  ( 5 min )

What if your database actually brought you, not just similar words but meaning, intent, and similarity? Science fiction no longer. That’s what vector databases bring, and it’s transforming the work of data scientists handling unstructured data, whether pictures and sound or customer feedback and code. When I first heard the term vector databases, I did not consider it seriously as I assumed it was a hype following AI. I went ahead and tried it out and even implemented it in a semantic search application, and I just could not expect the experience to be so different. Now, “searching” never seemed quite so much like reading out of the dictionary as it seemed to be conversing with someone who knows what you’re discussing. Let’s break down what a vector database is, why you’ll want to care, an…  ( 6 min )

📌 This is a follow-up to my previous post: How Docker Works Internally Before you can install Docker Engine on a fresh Ubuntu (or Debian-based) system, you need to set up Docker’s official apt repository.

Welcome back. In the last part of this series, we looked at the Vision column of the Architecture Work Canvas—where you define goals, constraints, stakeholders, and outcomes. Today, we’re moving into the second column: Business Architecture. This is the bridge between business intent and technical design. And honestly, it’s where a lot of architecture efforts start to fall apart. The truth is, IT solutions exist to serve business processes. But many architects were never really trained to map those business connections. They get handed a goal or a problem, and they dive straight into systems and tools—without stopping to ask how the business actually works. And that’s where things go wrong. You end up with solutions that are technically solid but completely disconnected from what users an…  ( 5 min )

Solving the Flutter did_send Crash: A Deep Dive into Isolate Race Conditions TL;DR: A race condition in Flutter isolate communication was causing fatal did_send crashes in our production sports app. The fix required async coordination, proper cleanup sequencing, and a critical 100ms delay. Here's how we solved it. Imagine this scenario: Your Flutter app is running smoothly in production with thousands of daily users. Everything works perfectly until users start reporting random crashes when navigating to specific screens. The crash logs show a cryptic, terrifying error: [FATAL:flutter/lib/ui/window/platform_message_response_dart_port.cc(53)] Check failed: did_send. This wasn't just any crash—it was a fatal engine error that would completely terminate the app. No graceful error handlin…  ( 6 min )

Introduction Testing is a critical, yet overlooked, part of modern app development as it helps prevent bugs from slipping through the cracks and affecting users. It should be an integral part of a healthy code base and must be maintained like any other code written in the repository. Flutter provides a robust framework and excellent tools for writing and running tests at different levels of your application. Whether you're building a small app or scaling a large codebase, testing ensures that your code is reliable, maintainable, and free from regressions. In this article, we'll explore the general idea of automated testing and the three main types of testing in Flutter: Unit Testing, Integration Testing, and Widget Testing.

Statistics, as a whole, is one of the subjects I enjoy most as a data scientist. In this article, we explore measures of central tendency which are part of the fundamentals of statistics and get to understand how they are used. Measures of central tendency are values that are used to summarize data in order to understand how the data is distributed. They include; mean, median and mode i) Mean The mean is used when you want to see where the average value of the data set lies which helps you understand the nature of the distribution. It is also used to fill in missing values in data set where the distribution is a symmetric and has no outliers. Calculating mean using python library numpy: import numpy as np num = [2,2,3,4,8,5] mean = np.mean(num) print(mean) ii) Median Calculating median using python library numpy: import numpy as np num = [2,2,3,4,8,5] median = np.median(num) print(median) iii)Mode It refers to the most repeated value in a data set. The mode is also used to replace missing values depending on how many times it appears and the nature of the distribution. Calculating mode sing python library statistics: import statistics num = [2,2,3,4,8,5] mode = statistics.mode(num) print(mode) In conclusion, the measures of central tendency are fundamental when exploring your data and can tell you so much about it. I hope this article has helped to shed some light on your understanding of the measures of central tendency and their importance!  ( 3 min )

Hey folks! 👋 TypeScript in real-world codebases, I’ve noticed that some bugs don’t scream—they whisper.

I Joined the World’s Biggest AI Hackathon… and Started 10 Days to the Deadline 😅 I haven’t been active for a while here, but like I promised in my last post, I’ll be sharing my experience participating in the world’s largest AI Hackathon hosted by Bolt. How it started... Then came the update: the Hackathon dates were pushed to June 1st–30th. Then I got an email... During my #100daysofcode, I had started a personal project, a solution to a problem I personally face: organizing screenshots. Originally, I had another idea in mind for the Hackathon, something dear to my heart. I really wanted to see that app come to life and watch people actually use it. But the project was way too large to finish within the time frame. So I decided to go with the project I was already working on, the one about organizing screenshots. 30 days. 12 days Already gone. 10 days to the end of the Hackathon. Why? 😆😅 Let’s just say… life was life-ing. Catch me in Series 2 where I share exactly how I managed the last-minute pressure.  ( 3 min )

A few weeks ago, I was re-watching Ford v Ferrari (a great movie, by the way), and there's this scene where Carroll Shelby explains that winning isn't just about having the fastest car. It's about the perfect lap. The driver, the weather, the tires, the brake assembly, and even the timing of gear shifts matter. Everything matters. That got me thinking about vector databases. We spend so much time debating Postgres vs. Redis vs. Pinecone vs. Weaviate vs. Qdrant vs. Milvus, comparing benchmarks, arguing about which one is "fastest." But here's the thing: we're missing the forest for the trees. Like in racing, the database is only one component of a complex system.

I'm so proud of myself I could cry! Granted, all I did was click the create repository button, add a generic title like: First Github repository and the rest was history... and a lot of confusion BUT I DID IT and I'm so proud! 🤗 Confused but proud. Great question. Well I've been trying to learn how to code for a while now and strangely enough after completing a Level 3 Diploma in software development in February this year, somehow I've never actually tried to build anything. For some reason I've been stuck dabbling in multiple free online learning websites which are great, dont get me wrong. However, I felt it was time to actually give this web designing a go or else I'll be stuck just searching for more free online courses, signing up to them and most likely never really finishing them and if, by some miracle I do complete them, I still havent built an actual, even basic webpage. Start using my Github account ✅ Create a repository ✅ Build/make a webpage ☐ Build another webpage ☐ And another... ☐ And one more for good measure ☐ Make updates to my Dev.to page each time to document this historic attempt at attempting to build websites. ☐ So about 5 projects in total and I think that will not only be beneficial learning experience but will be an opportunity for me to put myself out there and I fail (which I hope I wont but might do) at least we tried! Hopefully this blog post will also add as a source of accountability for me I dont really have a timeline but I'd say about 60 days should do it or maybe I'm being to naive? If any experienced individuals in coding or web design could let me know if this is doable, please let me know. Thank you in advance!

When AWS made the Kiro announcement, I was more than excited to try it out. As I write this blog, it is still in it's preview stage. I was able to download it before its access was limited for fine-tuning. I would love to share my experience so far. We are in the awesome age(some would think scary😅), of code-native AI agents. Think of it as a coding partner that is integrated to your coding environment such as your terminal or IDE. It has a codebase-wide understanding of your project which means it understands your project structure and gets the context across multiple files. Kiro is one of these cool tools. When I downloaded it, I signed in using my AWS Builder ID. There are other sign-in options including Google and Github. I loved this option that allowed me to import my configs from V…  ( 4 min )

From a conversation with perplexity.ai about a hypothetical programming language. Referential transparency is considered a staple in pure functional programming. It typically assumes immutability. But mutability is often more efficient than immutability, since it involves changing data structures in-place rather than always having to create copies. So, could referential transparency be combined with mutability, if the language was sufficiently restrictive..? —- If a function mutates its input but is forced to return that mutated input as part of its result, and if the caller is constrained to never reuse the original input after calling the function, then this can preserve referential transparency despite the mutation. This is because: Referential transparency means you can replace a fun…  ( 5 min )

Intro: PHP 8.4's New DOM\HTMLDocument Class PHP 8.4 quietly introduced a powerful new class: DOM\HTMLDocument. Unlike the traditional DOMDocument, this class is tailor-made for parsing HTML5, not XML, and brings a more forgiving and intuitive DOM interface to modern PHP. Note: This requires PHP 8.4+ and the dom extension to be enabled. DOM\HTMLDocument is more HTML5-native than the classic DOMDocument, which is XML-centric and strict about malformed markup. If you’ve ever fought with DOMDocument silently failing or auto-correcting tags, this new API is for you. I created a GitHub repo showing how to: Load and parse HTML5 files Access elements like and Extract tags Cleanly render DOM elements as HTML GitHub Repo: github.com/Fishbite/php-dom-htmldocument-examples use DOM\HTMLDocument; require __DIR__ . '/vendor/autoload.php'; $dom = HTMLDocument::createFromFile('./html/sample.html'); $head = $dom->getElementsByTagName('head')->item(0); foreach ($head->childNodes as $child) { if ($child instanceof DOM\Element) { echo "First tag in : tagName}>\n"; echo $dom->saveHTML($child); break; } } extract_head.php: Show the first child of extract_title.php: Grab the text list_meta.php: List all tags sample.html: Minimal HTML5 doc for testing composer.json: Basic autoloading config You can run each file individually from the command line or route them through a browser if preferred. There’s very little official documentation or community content around DOM\HTMLDocument, so this is a good time to explore it together. Feedback, suggestions, or PRs are more than welcome! Let’s help get the word out and make working with HTML in PHP a whole lot nicer.  ( 3 min )

Most AI Agents used to break the moment you tried plugging them into a real app. The issue was the lack of shared protocols. But that’s changing fast. Over the past year, protocols like AG-UI (user interaction), A2A (agent-to-agent communication), and MCP (for tool access) have changed the ecosystem. So I took the chance to learn these protocols and understand how everything fits together. This post covers everything I picked up about protocols (AG-UI, ACP, A2A, MCP). You will also find a collection of the best educational repos for learning & building AI Agents. This list will give you the foundations and tools you need.

USPTO to Overhaul Design Patent Search with AI Image-Based Tool in 2025 A major shift in intellectual property is coming as the USPTO embraces AI to solve one of the oldest challenges in design patent law. For decades, securing a design patent has involved a notoriously difficult step: the prior-art search. Unlike utility patents defined by text, design patents protect an object's unique visual appearance. This has forced inventors and examiners to rely on a clunky, often imprecise system of classification codes and keywords to find visually similar designs. The process is time-consuming, expensive, and akin to searching for a needle in a haystack with a text-based magnet, often leading to missed prior art and weaker patents. Everything changes in October 2025. The U.S. Patent and Trademark Office (USPTO) is set to launch a revolutionary tool that leverages artificial intelligence for image-based searching. Instead of fumbling with codes and descriptions, users will be able to upload an image of a design, and the AI will scan the entire database for visually similar precedents. This marks a monumental shift from an abstract, text-reliant process to a direct, intuitive, and powerful visual comparison engine. The implications are profound. For creators, this new AI tool promises to democratize the patent process, making prior-art searches faster, more accurate, and more accessible, leading to stronger applications. For USPTO examiners, it offers a massive leap in efficiency that could slash backlogs and improve the quality of granted patents. This bold step not only modernizes a critical government function but also sets a new global standard for how intellectual property offices can harness technology to better serve innovators.  ( 4 min )

Let's get straight to it.. Accss Control, What does it mean? So, let's put it this way, you saw this blog, and as you're reading it, you probably saw the typo i wrote Accss, and if you're me, you'd be thinking of editing it. Making it readable, so indirectly you want to edit my blog post 😏. But here's the critical question: Should you be able to? This is where Access Control fundamentally comes into play. Access Control is the gatekeeper that determines who can access what resources, and what actions they're permitted to perform. It's not just about letting people in; it's about defining their privileges once they're inside. In the context of web applications, access control is dependent on authentication and session management. Authentication confirms that the user is who they say they are. Session management identifies which subsequent HTTP requests are being made by that same user. Have you heard of Vertical Privilege Escalation? Then there's Horizontal Privilege Escalation Unprotected Functionality https://insecure-website.com/admin, https://insecure-website.com/admin or just using a wordlist to brute-force sub-directories that contains administrative functionalities or simply checking the JavaScript on the user interface: var isAdmin = false; if (isAdmin) { ... var adminPanelTag = document.createElement('a'); adminPanelTag.setAttribute('href', 'https://insecure-website.com/administrator-panel-yb556'); adminPanelTag.innerText = 'Admin panel'; ... } Parameter-based Access Control Methods https://insecure-website.com/login/home.jsp?admin=true, the parameter admin is set to true. Which means that when a non-administrative user browses to the URL, the user gains admin privileges, due to the parameter admin being set to true. This approach is insecure as the web URL can be modified to gain access. So with that, you've got an idea on Access Control. Without robust access control, anyone spotting that typo could theoretically change it, or worse, delete the entire blog post.😏  ( 3 min )

Performance testing maturity: A comprehensive guide When Amazon's Prime Day experiences slowdowns, they lose $1.6 billion annually for every 100ms of delay. When banking applications crash during peak hours, the consequences ripple far beyond technical teams into regulatory compliance, customer churn, and damaged reputation. Yet despite these high stakes, most organizations approach performance testing with ad hoc methods and reactive measures that leave critical systems vulnerable to failure. The reality is that most organizations still operate at the initial maturity level of performance testing, relying on sporadic testing driven by urgent issues rather than systematic testing processes. Understanding performance testing maturity models Performance testing maturity models serve as stra…  ( 13 min )

What is MCP Model Context Protocol (MCP) is a new open standard that makes it easier for AI systems to connect with external data and services.  In simple terms, MCP acts a bit like an API for AI models – it provides a standard “language” for AI programs to access tools or data from the outside world. This means developers no longer have to write one-off integrations for each service; instead, an AI can use MCP to securely interface with many different data sources through a unified protocol.  Think of MCP like a USB-C port for AI applications: it’s a single, standardized way to plug an AI model into various databases, apps, or APIs. MCP was developed by Anthropic (the AI company behind Claude) and open-sourced in late 2024. It quickly gained traction as a standard for connecting large l…  ( 6 min )

Global Installation npm install -g @angular/cli A global install allows you to run Angular CLI commands from anywhere on your system. npm install @angular/cli This installs the CLI only within your project directory.

Today, I explored the Vec type in Rust — a powerful and flexible way to store a list of values in memory. Vectors are dynamic arrays and are part of Rust's standard library collections. Let’s break down everything I learned. 📦 What is a Vector? A Vector is a growable array type that stores multiple values of the same type, located contiguously in memory. They’re great for use-cases like: Storing prices in a shopping cart. Collecting file lines. Managing dynamic lists. 🛠 Creating a Vector Using Vec::new (Empty Vector with Type Annotations) let v: Vec = Vec::new(); Since no values are inserted yet, you must specify the type. Using vec! Macro (With Values) let v = vec![1, 2, 3]; Rust infers the type as Vec from the initial values. ✏️ Updating a Vector Use .push() to append elements: …  ( 5 min )

Want static analysis to run not just locally, but also on every pull request? Want bugs to be caught before they reach the main branch? In this article, we'll show how to set it up in the GitHub Actions pipeline. One effective way to use static analysis regularly is to integrate it into a Continuous Integration (CI) workflow, which delivers regular code merges into a shared repository, automated builds, and testing. CI typically runs a set of various tests, but it doesn't mean that testing should be our only safeguard. Static analysis can detect errors and potential vulnerabilities even before we run tests, which strengthens the overall process. Using static analysis in CI helps catch issues early, avoid pushing errors to the main branch, and boosts the overall project quality. However, r…  ( 11 min )

So you just discovered CustomEvent in JavaScript and feel like a wizard? Get ready — the browser has a whole toolbox of magic you haven’t explored yet.

Think about it: every time you've watched a company completely flip its game (hello, Netflix going from DVDs to streaming king), there's been some serious digital rewiring happening behind the scenes. Now AI's the secret sauce making that transformation faster, smarter, and way more powerful. Digital transformation is basically giving your business a complete makeover – new processes, fresh tech, and a mindset shift that puts data at the center of everything. AI supercharges this journey by acting as both the engine and the fuel for change. Here's where it gets interesting: 92 percent of companies plan to increase their AI investments over the next three years, but most are still treating AI like a side project rather than the backbone of their digital strategy.

Terraform has two ways to bring existing resources under Terraform management — using the Terraform CLI and the terraform import command, or using the import resource. Why might we need to import resources? if we already have a manually configured (the “clickops”) service that we want to bring under Terraform management (for example, the common history when it was done as a Proof of Concept, and then went into Production) if we have resources that were created with another IaC system, for example, CloudFormation if we lost our state file and need to restore it or if we split one large project into smaller ones and create new state files In addition to the Terraform CLI and the import block, there are tools like Terraformer and Terracognita that do some of the work themselves - but today we…  ( 9 min )

My almost-3-year-old has been having a blast with GCompris educational games and we recently showed him how to make simple sprites move around in Scratch. One day, he announced that he wanted to "make a red car game." Not play a red car game. Make one. This was something I'd been curious about—could a toddler actually use AI tools to create something real? Spoiler alert: he absolutely could. The beautiful thing about modern AI coding tools is that they've eliminated the biggest barrier between kids and creation: syntax. My son doesn't need to understand semicolons or bracket placement—he just needs to be able to describe what he wants. Here's exactly how we set up his development environment in about 10 minutes: Sign up for Github (Yes, my toddler has his own Github account ❤️) Download Vi…  ( 8 min )

The Mistake It was 5 AM. I was tired, a bit overconfident, and really wanted to see my ASG + ALB setup in action. So I skipped a pretty important step - testing the EC2 Launch Template, and jumped straight into building the full infrastructure. Once everything was up, I opened the ALB’s DNS URL… and saw a blank page. After some digging, I realized: the EC2 Launch Template I used didn’t have my server. It was empty. That’s when I learned that launch templates don’t store your file system. If you want your server to work, you need to create a proper AMI or add user data to install everything during boot. I was learning about AWS Auto Scaling Groups (ASGs). I already had a decent understanding of VPCs, subnets, route tables, IGWs, and NAT Gateways.

Hello, Today I want to share something that's become increasingly critical in our cloud-native world — securing internal tools and dashboards without the complexity of traditional VPN setups. Picture this: Your company has grown from a small startup to a mid-sized organization. You have internal dashboards, monitoring tools, admin panels, and various services running on Google Kubernetes Engine (GKE). Initially, maybe you secured these with basic auth or just left them on internal networks. But as your team grows and remote work becomes more common, you realize you need something more robust, more scalable, and frankly, more professional. That's where Google's Identity-Aware Proxy (IAP) comes in, and today I'll walk you through implementing it using Infrastructure as Code with CDKTF. Ident…  ( 10 min )

📌 Problem 1: Generate Alternating Triangle Write a function that takes a number n and prints a triangle of size n where each row contains alternating 1s and 0s, starting with 1. To generate this alternating binary triangle, follow these steps: Create two variables: pattern → an empty string to accumulate the full result. currentValue → a temporary variable initialized inside each row to 1. Outer loop (i from 0 to n - 1): Controls the number of rows. For each row: Set currentValue = 1 before entering the inner loop. Inner loop (j from 0 to i): Controls the number of columns (or characters) in that row. Append currentValue to pattern. Flip currentValue: If currentValue === 1, set it to 0. Else, set it to 1. 📥 Input: n = 5 📥 Output: 1 10 101 1010 10101 /** * Generates a triangle pattern with alternating 1s and 0s * @param {number} n - Number of rows in the pattern * @returns {string} - The generated triangle pattern */ function generateAlternatingTriangle(n) { let pattern = ""; for (let i = 0; i < n; i++) { let currentValue = 1; // Start each row with 1 for (let j = 0; j <= i; j++) { pattern += currentValue; currentValue = currentValue === 1 ? 0 : 1; // Toggle value } pattern += "\n"; // New line after each row } return pattern; } // ✅ Test Case const n = 5; console.log(`Pattern for n = ${n}:\n`); console.log(generateAlternatingTriangle(n));  ( 3 min )

In any data analysis or statistical endeavour, understanding the behaviour of a dataset is fundamental. One of the primary ways to summarise and interpret data is through measures of central tendency, which identify the central or typical value around which data points cluster. The three main measures of central tendency are mean, median, and mode. The mean, commonly known as the average, is calculated by summing all values in a dataset and dividing by the number of values. For example, if data represents the ages of participants in a survey, the mean gives the general age around which most participants’ ages are spread. Advantages: Uses all data points, making it highly representative when there are no extreme outliers. Limitations: Sensitive to outliers, which can distort the mean away f…  ( 4 min )

If you've been working with modern front-end development or UI/UX design, you've likely heard the terms Component Library and Design System tossed around—often interchangeably. But despite some overlap, these two concepts serve very different purposes. A component library is a collection of reusable UI elements. Think of it as your project’s toolbox filled with pre-built visual parts: buttons, inputs, dropdowns, modals, cards, and so on. These components usually follow a consistent visual style and are often built using frontend frameworks like React, Vue, or Angular. The goal is to avoid reinventing the wheel every time you need a button or form input. Component libraries help teams: Move faster by reusing elements Maintain consistency across screens Reduce front-end bugs related to layou…  ( 4 min )

In CI/CD Systems, there is a concept of pipelines. Pipelines define the steps of how code changes throughout the entire CI/CD process. Multiple systems like Github Actions, GitLab CI/CD, Jenkins etc all have this functionality of pipelines natively embedded within them, something that Conveyor CI currently lacks. You could engineer a walkaround to implement your own pipeline-like functionality in Conveyor but natively, this functionality does not exist and this is a serious downside existing within Conveyor. This got me thinking, how could I implement it. As you might guess from the name, Conveyor CI was inspired by how a conveyor system in an industry works. Take an example of a car manufacturing factory, the skeleton of the car moves along the conveyor system and at each step there is a …  ( 9 min )

You’ve probably used multi-factor authentication (MFA) on the device you’re using right now. Maybe you have to enter your password and then scan your fingerprint to access a banking app, or you log into your email with your password followed by a quick code from an authenticator app. We use MFA every day to prove that we are who we say we are. But what about the actions after you log in? For a business handling payments, the most sensitive operations aren't just at the front door; they're inside the house. Actions like issuing a refund, transferring funds, or changing a merchant's bank details carry immense risk and shouldn't be handled with standard permissions. Instead, they require you to apply MFA to specific, high-risk actions within your internal tools. In this tutorial, you’ll lea…  ( 11 min )

🕳️ It all started with a rabbit hole… One evening, I fell into r/unixporn. You know the kind of community where your terminal looks like a Blade Runner set and every screenshot is a mood board. I loved dark themes. But most of them felt too cold, more like a corporate hacker aesthetic than a place I’d want to spend hours in. 🔥 The idea behind Emberstone Mood: dark, yes… but inviting. Goal: readable, balanced contrast, pleasant for long sessions. Accessibility: good enough to avoid eye strain and UX nightmares. The name? Emberstone : the glow of embers in the dark. 🛠️ What I wanted to cover I didn’t want just a VS Code theme. I wanted an ecosystem: ✔ Terminals: Konsole, Hyper, Warp, iTerm2 (coming soon) ✔ Browsers: Firefox ✔ Comms: Slack, Discord (coming soon) ✔ Media: Spotify via Spicetify ✔ Websites (Stylus): ChatGPT, Reddit, Twitter, GitHub, YouTube (WIP) A theme that doesn’t stop at your IDE but extends across your digital environment. ✅ The good and the… real-world stuff Upsides: Challenges: 📚 What I’ve learned Theme design is craft: it’s not “just colors.” Massive respect to theme maintainers: every theme you install in 3 clicks hides hours of invisible work. 🚀 What’s next?

Every engineer has their perfectionist phase. I certainly did. There's a season early in your career where every line of code must be beautiful, every edge case handled, every abstraction future-proofed. That desire to do things “right” feels noble - but over time, experience teaches you that chasing perfection is often just a well-disguised form of avoidance. At some point you realize: perfection is the enemy of done. That doesn't mean we should write careless code. There's still pride in craftsmanship. But what shifts is your understanding of what done really means. You start seeing the bigger picture - that your work exists in a system with deadlines, dependencies, and a team relying on forward momentum. That no feature will ever be perfect the first time, or even the tenth. One of the …  ( 4 min )

1. Portfolio Governance Governance defines how the portfolio is controlled and managed. It includes the roles and responsibilities of the portfolio manager, steering committees, and executives. This structure ensures accountability and clear decision-making authority. Projects and programs must support organizational goals. Strategic alignment ensures that every initiative in the portfolio contributes to overall business priorities. A portfolio management plan sets out clear guidelines for selecting which projects enter the portfolio. It also provides ranking criteria based on ROI, risk, strategic value, and resource requirements. This component details how resources—both financial and human—will be distributed among projects. It helps avoid conflicts, over-allocation, or underutilization of resources. The plan includes a risk management strategy that identifies potential risks, their impact, and mitigation measures at the portfolio level. It establishes key metrics to monitor portfolio performance. Regular progress reports and dashboard tracking are integral to this component. Effective communication among stakeholders ensures transparency and alignment. The communication strategy defines how updates, risks, and results will be shared.  ( 3 min )

In analytical systems, dimensional data rarely remains static. Customer profiles, product attributes, account statuses—they all evolve. Without proper handling, these changes can corrupt the historical integrity of reports and models. Slowly Changing Dimensions (SCD) are engineering strategies for managing these changes. While fact tables capture discrete events like transactions or clicks, dimension tables provide the descriptive context: who, what, where, and when. If these contexts are overwritten, past facts lose their original meaning. SCD techniques define how to handle such changes: overwrite, preserve history, or track specific values. The chosen approach impacts storage, query complexity, and trust in analytical outcomes. Accurate handling of dimensional changes is critical in do…  ( 9 min )

You know, as a web developer, I've been using a bunch of Python packages to scrape website data for years. And now, thanks to the insane development in AI, there is a sudden rise in the need to access real-time data and build AI models or different businesses out of it. You may have heard that: Google is paying $60 million per year to get real-time access to Reddit's data DeepSeek team is stealing OpenAI data for training their own AI model And more Well, there are multiple news stories like this, and we can say that every big company is in the process of accessing tons of real-time, filtered data. But most of us can't spend millions to gain real-time data, and we are not programmers, so we can't use Python packages, and more. That's where you can use a number of web scraping tools that us…  ( 8 min )

It’s the world of Brain-Computer Interfaces (BCIs), and it’s moving fast. A Brain-Computer Interface (also called a Brain-Machine Interface) is a system that lets your brain talk directly to a device—skipping over muscles, speech, and gestures. It picks up electrical activity from the brain, decodes it using smart algorithms, and turns it into actions.

TL;DR: SSL certificates secure your website’s connection, but managing them can be tricky. Domains also have expiry dates that require attention. This post breaks down key concepts around SSL and domain expiry, common pitfalls, and best practices to keep your web services secure and accessible. SSL (Secure Sockets Layer) certificates encrypt data exchanged between browsers and servers, preventing eavesdropping and tampering. Without a valid SSL certificate, browsers will warn users that your site is insecure. Key point: Certificates have a validity period (often 90 days for Let’s Encrypt, or 1 year+ for paid certs), and must be renewed before expiry to avoid downtime. Your domain name (for instance: mydomain.dk) registration also has an expiry date, independent from SSL certificates. If th…  ( 4 min )

Getting a Verified Mark Certificate (VMC) is essential if you want your brand’s logo to appear next to authenticated emails. This enhances trust and combats phishing. Here’s a simplified overview of the process in six key steps: 1. Become DMARC Compliant Before applying for a VMC, your domain must have DMARC set up. DMARC (Domain-based Message Authentication, Reporting & Conformance) helps stop email spoofing. You must first: Set up SPF (Sender Policy Framework) by listing all IPs allowed to send emails from your domain. Configure DKIM (DomainKeys Identified Mail) to ensure email integrity using cryptographic signatures. Add a DMARC TXT record in your DNS with a policy like p=quarantine or p=reject and monitor reports to fine-tune your email authentication. 2. Trademark Your Logo To be eli…  ( 4 min )

The day I discovered that JPEG compression artifacts could solve a million-dollar fraud case It was 2:34 AM when the Slack message arrived: "Emergency. Suspected fraud. Need your image expertise ASAP." What started as a routine request to optimize some product photos for an e-commerce client turned into a digital forensics investigation that would save the company $1.2 million and land me in a courtroom as an expert witness. The smoking gun? A tiny inconsistency in JPEG compression artifacts that revealed the supposedly "original" product photos had been heavily manipulated. That night, I learned that image optimization isn't just about performance—it's about truth, evidence, and the digital breadcrumbs that compression algorithms leave behind. // How image optimization creates forensic ev…  ( 10 min )

How to Persist Pinia State Ibrahim ・ Jul 22 #vue #frontend #javascript #web  ( 2 min )

Sometimes, we want to persist the Pinia state so that when the page is closed, the state still exists when the page is restored. This can be useful for states like authentication tokens, shopping carts, and more. This can be implemented using a plugin called Pinia Plugin Persistedstate. This plugin persists Pinia store state using localStorage or other storage options. To get started, install the plugin first: npm install pinia-plugin-persistedstate Next, import the plugin and use it with the Pinia instance: import { createPinia } from 'pinia' import piniaPluginPersistedstate from 'pinia-plugin-persistedstate' const pinia = createPinia() pinia.use(piniaPluginPersistedstate) Next, add the { persist: true } option to the store that should be persisted: import { ref } from "vue"; import { defineStore } from "pinia"; export const useStore = defineStore( "auth", () => { const loggedIn = ref(false); const accessToken = ref(null); return { loggedIn, accessToken }; }, { persist: true } ); In the example above, the auth store's state will be automatically saved to localStorage. For advanced usage, such as customizing the storage, read the full documentation at https://prazdevs.github.io/pinia-plugin-persistedstate.  ( 3 min )

Learn how to update database schemas using prompts with GitHub Copilot and create GitHub pull requests with matching Python model classes. Updating a database schema as part of your development process often feels more complicated than it should be. If you’ve ever worked with tools like SQLAlchemy, Alembic, or EF Core, you probably know the drill: you first update your model classes in code, then generate a migration file, and finally apply those changes to your database. It's not a terrible process—but it's slow, easy to mess up with the correct migration order, and repetitive. You constantly have to switch contexts: from writing model code, to terminal commands, to reviewing raw SQL. Wouldn’t it be easier if you could just describe what you want in English and let your tools handle the r…  ( 6 min )

In C#, var is statically typed and determined at compile-time, ensuring type safety. dynamic allows runtime flexibility but lacks compile-time checks, increasing risk. object is the base type for all data, requiring casting. Choose based on whether you need type inference, flexibility, or general-purpose storage with conversions. Here's a clear and concise explanation of var, object, and dynamic in C#, with individual content for each: Var Type is inferred at compile-time based on the assigned value. Still strongly typed; can't change type after initialization. Improves readability when the type is obvious or long. Dynamic Type is resolved at runtime, no IntelliSense or compile-time checks. Can change types and properties freely. Ideal for working with COM, JSON, reflection, etc. Object Can store any data type (value or reference). Requires explicit casting when retrieving the original type. Useful for general-purpose storage. Conclusion Choosing between var, object, and dynamic depends on your coding needs. Use var for concise, type-safe code; object for storing any type with casting; and dynamic for flexible, runtime-bound operations. Understanding their differences helps you write more maintainable, efficient, and error-free C# applications.  ( 3 min )

How to preserve human visual memory when the infrastructure fails and bandwidth becomes more precious than water The year is 2029. The Great Network Collapse has reduced global internet bandwidth to 1% of pre-collapse levels.

Europe's AI ambitions are heating up! The European Commission is seeing a flood of interest in their AI Gigafactories initiative with 76 expressions of interest covering 60 potential sites across 16 EU countries. These aren't small players either - major European data center operators, telecom giants, power companies, and global tech firms are all vying to be part of Europe's AI renaissance. Collectively, they're planning to acquire at least three million GPUs to build computing muscle that could rival anything currently available. The AI Gigafactories will be more than just computing centers - they're designed to be complete ecosystems where hardware, software, data, and talent converge to develop sovereign AI capabilities for Europe rather than relying on American or Chinese technology. Of course, energy consumption remains a major challenge, but several proposals reportedly include innovative cooling solutions and partnerships with renewable energy providers. While the formal call for establishing these Gigafactories isn't expected until late 2025, the race is on. In AI, being second or third to market isn't just about pride—it could mean permanently relying on foreign technology rather than developing sovereign capabilities. What do you think about Europe's AI strategy? Is this the right approach to compete globally? Share your thoughts!

Using LangChain This post is a follow-up to this one from two weeks ago which detailed how to make a medical chatbot using SurrealDB and LangChain using Python. Rust developers have an option to do the same too, thanks to a crate called langchain_rust which as of last year includes support for SurrealDB as a vector store. This implementation doesn't (yet!) include graph queries, but we can still use classic vector search to find recommendations for treatment for a patient. To start off, use a command like cargo new medical_bot to create a new Cargo project, go into the project directory and add the following under [dependencies]. anyhow = "1.0.98" langchain-rust = { version = "4.6.0", features = ["surrealdb", "mistralai"] } serde = "1.0.219" serde_json = "1.0.140" serde_yaml = "0.9.34" s…  ( 9 min )

So I am building a todo app(very common, I know), and in that, there must be a feature for due dates. Due dates are a must, in the sense that they provide a deadline for when the task must be completed. I implemented a color based system to differentiate whether a task is currently active (due date is in future): denoted by green color, same day (due date is the same as creation): denoted by orange, overdue (due date is over): denoted by red and an overdue indicator I implemented it and it worked alright but I saw that the task created today also had an overdue indicator. I thought, what's happening here, and then I realized the time factor is involved in the comparison, if you compare two date objects there always be time involved and it will not be desired in every case (like my case) const compareDate = (date) => { const current = new Date() const due = new Date(date) if(current === due) return 'orange' if(current > due) return 'red' //here basically return 'green' } But if you use .toDateString() to compare only date will be compared and time factor is eliminated: const compareDate = (date) => { const current = new Date() const due = new Date(date) if(current.toDateString() === due.toDateString()) return 'orange' if(current > due) return 'red' return 'green' } This fixed the problem for me, so if you're facing the same problem and this helps, you can follow for more dev tips just like this!  ( 3 min )

Clear, comprehensive documentation provides the domain context that AI models need to reason accurately. It helps define ground truth for annotations, improves consistency during fine-tuning, and guides ethical usage. From API references to onboarding guides, documentation becomes a source of structured knowledge that LLMs can ingest and learn from. So why is documentation a game-changer for fine-tuning LLMs? ✅ Grounded Knowledge ✅ Annotation Clarity ✅ Audibility & Trust 📊 Real-world impact: 🧬 In healthcare, LLMs grounded in clinical documentation reduced diagnostic errors by up to 30%. 💻 Training on well-documented open-source repos outperformed under-documented ones on code generation benchmarks. ⚠️ Poor or outdated docs = hallucinations, bias, and compliance gaps. 🛠️ Best practices for AI/ML teams: Treat documentation like code: version it, review it regularly, and update it frequently. Don’t forget to document: data sources, licenses, prompts, limitations, and annotation guides. As AI becomes embedded in every industry, documentation is no longer a nice-to-have; it’s a strategic advantage. How are you integrating documentation into your AI workflows? Any lessons, wins, or hard-learned mistakes to share? Let’s spark a conversation 👇  ( 4 min )

In this series, I will walk through the implementation of a mathematical parser in C/C++ that I learned from Udemy course with an instructor, Abhishek. My completed code is in my GitHub. I do not get sponsorship from him, but I think his courses are very good for learning C/C++. I recommend checking out his courses, there are a lot of interesting projects. Let's begin with the expectation of this project. By the end of this series, you will have your mathematical expression parser that parses an input string and evaluates the result, including inequality and logical expressions as demonstrated in the following picture. Try parsing the input string expression in the following order: logical, inequality, and math expression. If the parsing fails, try the next expression. During parsing, create a lexical stack using a backtracking algorithm. Convert a mathematical expression from infix form to postfix form, which does not need parentheses to reduce ambiguity of operator precedence. Create a lexical tree from the postfix form. Evaluate the result by traversing the tree in postorder.  ( 3 min )

Introdução A eterna busca por reduzir o código boilerplate em Java ganhou duas ferramentas poderosas: Java Records (introduzidos no Java 14 e estabilizados no Java 16) e Lombok (biblioteca amplamente adotada há anos).

My colleague & me were on the Socrates un-conference in Soltau, Germany. This was our 2nd Socrates, as we were both at the UK version last year. Comparison with the UK conference is not very interesting: There were more people than in the UK (this is usually the biggest Socrates by far) and the hotel was new, built specifically for conferences & gatherings. Other than that the venue type was similar and the people were as smart, as kind & as inviting as in the UK. Comparison with other conferences and life experiences in general is close to impossible. The German Socrates is as radical as the UK Socrates in more than one aspect. Socrates is a complex endeavour and describing it is difficult. Hence I will do the engineering thing and analyse it.

I've been using vanilla Playwright for almost two years now, and when Playwright MCP was introduced, I was immediately fascinated. The idea of letting an LLM write and execute your tests just by chatting with it felt straight out of science fiction.

While the tech is undeniably impressive, I couldn't shake the feeling that something wasn't clicking for me.

Introdução Ao desenvolver aplicações modernas, especialmente APIs backend ou apps web/mobile que lidam com upload e download de arquivos, um desafio recorrente surge: como garantir segurança, escalabilidade e controle de acesso, sem criar um monólito de permissões no backend?

👉🏽 Try Rebase for free, no credit card needed If you have used AWS, you know about Elastic IPs. These are public IPs you can stick to your EC2 instances, load balancers, or NAT gateways. They let you keep the same public IP, even if you stop and start your resources. This comes in handy if you want to keep your DNS or firewall rules simple. The thing is, Elastic IPs are not free if you leave them unused. AWS will charge you for any Elastic IP that is not attached to a running resource. If you forget to clean up, your bill goes up for no good reason. Removing unused IPs is one of those things people put off, especially if you have a bunch of them across different regions. With Rebase, you do not have to mess around in the console or write a script for it. You just give it a prompt and it handles everything for you. Here is how it looks in action. First, just ask the agent to show you the VPCs and Elastic IPs you have. Now, ask the agent to release all the unassociated Elastic IPs. That is all it takes. You can check in the AWS Console to confirm they are gone.  ( 3 min )

Context: when the pipeline stops because of a single record In a common large-scale data ingestion scenario using Apache Beam, we faced a classic issue: a single malformed record caused the entire pipeline to fail. It was expected that some records might contain errors, but the pipeline was assuming everything would work perfectly. There was no fallback, no distinction between business or technical errors, and no isolation for problematic data. This led us to the key question: how do we keep the pipeline healthy even in the presence of predictable failures? Prevent exceptions from halting the processing of all data Separate technical failures (e.g., API errors) from business logic issues (e.g., invalid value) Log errors in a structured format for analysis and possible reprocessing Implem…  ( 5 min )

Introduction MediaWiki provides an excellent foundation for collaborative publishing, but it lacks native real-time functionality. Editors must manually refresh pages to check for changes, and administrators are not immediately notified of critical edits or vandalism. This article demonstrates how to build a real-time notification system for MediaWiki using extension hooks, a message broker like Redis, and a WebSocket server. The implementation remains modular and decoupled, enabling flexible integration and scaling. In collaborative environments such as knowledge bases, wiki farms, or moderated documentation portals, visibility into changes as they occur is critical. While MediaWiki includes the Echo extension for notifications, it does not provide real-time push functionality. Instead,…  ( 6 min )

Hello everyone, As a novice Python student myself, I'm currently conducting academic research on common error types in Python through surveys and interviews. Your insights and experiences are incredibly valuable, and I’d love to learn from the community. My study aims to understand the underlying causes of common coding errors, including those rooted in critical thinking, which can be a significant barrier to problem-solving. The knowledge from this research can greatly benefit programmers by helping them pinpoint errors, correct mistakes more easily, avoid bigger errors and longer debugging sessions, and ultimately increase their expert deduction capabilities. If you're available and interested in sharing your thoughts, please let me know when you might be free to chat or feel comfortable taking part in a short interview. Thank you for your time and for helping improve our collective understanding!

At the end of 2021, I joined a young fintech startup with a brilliant idea: build a lending as a service platform. The concept was fresh, bold, and quite unique in Latin America. By integrating with payment providers, we could access anonymized transaction data from small businesses and assess their cash flow. Based on that, we offered them credit, something they couldn’t easily get from traditional banks. Repayments were automatically deducted as a percentage of their daily sales. I absolutely loved the idea. It was one of those concepts that make you stop and think, “Why didn’t I come up with this myself?” At the time, we were around fifteen people, with a single partner, and a huge list of things that still needed to be built. I came in to do what I enjoy most: build systems, automate e…  ( 5 min )

Optimize PDFs: Smart Compression Algorithms for Faster File Transfers In the realm of digital documents, PDFs reign supreme for their versatility and ubiquity. However, as developers, we often grapple with the challenge of bloated file sizes that slow down transfers and hog precious storage space. Today, we're going to dive into the fascinating world of PDF compression algorithms and explore practical techniques to optimize your PDFs for faster, leaner file transfers. Before we dive into the nitty-gritty, let's understand what we're dealing with. PDFs are complex documents that can contain a mix of text, images, vectors, and more. To compress them effectively, we need to understand the different elements and the algorithms that can shrink them down. Text: Usually the smallest part of a P…  ( 5 min )

Custom parser functions and hooks are powerful tools for MediaWiki developers aiming to extend functionality with precise control. Leveraging these mechanisms helps you integrate deeply with the core while maintaining clean, maintainable code. This detailed tutorial walks through creating a custom parser function and hook integration in MediaWiki, and explains best practices around security, performance, and maintenance. A parser function in MediaWiki allows you to introduce new syntaxes in wiki markup. A simple example is building a function that calculates and displays the square of a number. You register the function via extension.json, mapping a key such as "square" to a PHP handler class. In your class method, you accept the parser, frame, and parameters. Use intval to sanitize input …  ( 7 min )

AI notetakers to their meetings instead of showing up themselves. In a recent Washington Post article, the reporter recounts stories of meetings where these AI notetakers outnumbered the human participants - sometimes being the only other "attendees." But can an AI notetaker really be considered an attendee if it can't participate in conversations or contribute to the meeting? I would argue that an AI meeting agent that truly represents an absent person must actively participate by answering questions for them or providing context about their work. Essentially, this agent becomes a "digital twin" of the absent person. I found myself wondering: Is it already possible to create such a digital twin? (Spoiler: The answer is yes!). But I wanted to go even further. I aimed to build an AI meeting…  ( 7 min )

what is apache airflow --- Apache Airflow is an open-source platform for developing, scheduling, and monitoring batch-oriented workflows. Airflow’s extensible Python framework enables you to build workflows connecting with virtually any technology. A web-based UI helps you visualize, manage, and debug your workflows. You can run Airflow in a variety of configurations — from a single process on your laptop to a distributed system capable of handling massive workloads. With its core features like pipeline automation, dependency management, scalability, makes it a vital tool for data engineers. DAGS - A Directed Acyclic Graph(DAG), according to the official workflow documentation, is a model that encapsulates everything needed to execute a workflow. Schedule: When the workflow should run. Tasks: tasks are discrete units of work that are run on workers. Task Dependencies: The order and conditions under which tasks execute. Callbacks: Actions to take when the entire workflow completes. common uses of airflow Automation of ETL pipelines Data validation and transformation tasks schedule data analytics reports machine learning, model training and deployment. It is Python-based based enabling writing of workflows as code. Its web-based UI provides real-time monitoring and debugging capabilities. Separation of the web server and scheduler components allows for better resource allocation.

Agentic AI is redefining the foundations of software development—transforming roles, workflows, and the very paradigms by which we build applications. In response to this shift, a new discipline is emerging: Agent Engineering. This field focuses on the design, development, and supervision of intelligent agents—autonomous systems powered by large language models (LLMs), structured context, and real-time reasoning. These agents are not just components of next-generation systems; they are the system—capable of perceiving, reasoning, acting, and learning in pursuit of complex goals. Although the term “Agent Engineering” has surfaced in various corners of the AI ecosystem, its formalization is still in its early days. But as we step into 2025, one thing is clear: this is the year of AI agents. …  ( 10 min )

State management in React is one of the foundational concepts every frontend developer must master. As your component grows from simple to complex, choosing between useState and useReducer can greatly affect readability, performance, and maintainability. useState: Simplicity First The useState hook is ideal when your state logic is straightforward — a single value or a few unrelated values. It’s quick, easy to understand, and perfect for local UI states like toggles, inputs, or counters. const [count, setCount] = useState(0); return ( {count} setCount(count + 1)}>Increment ); useState Managing primitive values (strings, numbers, booleans) Simple form fields Toggling visibility (like modals or dropdowns) Less than 3–4 state va…  ( 4 min )

We have a stateful, configurable application running in our cluster. Kubernetes already provides a degree of resilience through self-healing—if a Pod disappears, the Deployment replaces it. But this raises a critical question: what does it mean for an application to be "healthy"? Right now, Kubernetes only knows if the container process has started. It has no idea if the application inside the container is actually working. What if your app has started but is stuck in an infinite loop? What if it's frozen and can't respond to requests? What if it needs 30 seconds to warm up and load data before it's ready to serve traffic? To Kubernetes, a running but broken application looks the same as a healthy one. This can lead to traffic being sent to Pods that can't handle it. To solve this, Kuberne…  ( 7 min )

WHAT IS A CLASS A class is like a blueprint for creating objects or an object constructor. It defines what data (variables) and actions (functions/methods) an object should have.Classes are a good example of object oriented programming using python. Classes are used for grouping code, to enable code reusability and scalability, and to facilitate the writing of clean code. When creating classes we use a special function called a the constructor method, this function gets called automatically and creates a new object.Basically innitializing the objects attributes. constructors are used to automatically set up object data, avoid repetitive code and ensure that every object starts with valid values. In Python, a class is created using the CLASS keyword.When creating a class its advised to us…  ( 4 min )

In early 2024, I made a decision that would shape the way I interact with the web: I chose to become a frontend developer. No, I didn’t start coding when I was six, nor did I attend a bootcamp or follow a polished learning path. Like most self-taught devs, I began with a curious mind, a laptop, and the endless rabbit hole that is YouTube. And I’m glad I took the leap—because frontend development became more than just a skill. It became a creative outlet, a technical challenge, and a form of expression. If you’re exploring where to start in tech, this post might help you understand why frontend could be the right choice for you too.

We talk a lot about what to learn: the latest frameworks, design patterns, clean code practices, you name it. But what about the things we need to unlearn? Sometimes, growth means letting go of habits, mindsets, or assumptions that no longer serve us. Here are a few things I believe we should actively work to unlearn: "More code = more value" We often feel productive when we're writing a lot of code. But real value comes from solving problems—not just producing code. Sometimes, deleting code is the smartest move you can make. "It works, so it's fine" Just because it works today doesn't mean it's maintainable tomorrow. Prioritize readability, clarity, and future-proofing over hacks that only solve the immediate problem. "Asking for help = weakness" You're not supposed to know everything. Asking for help isn't a weakness—it's how we collaborate and grow. The best engineers ask great questions. "More features = better product" Shipping too many features too fast can create clutter and confusion. Sometimes, the best feature is the one you decide not to build. "We’ve always done it this way" Technology evolves. So should we. Clinging to outdated patterns or tools just because they’re familiar can hold us back from better solutions. Learning is only half the journey. Unlearning makes space for better ideas, healthier habits, and cleaner code. What have you had to unlearn in your journey as a software engineer?  ( 3 min )

If your DevOps team is constantly firefighting alerts, chasing false positives, or losing sleep over noise, it might be time to rethink your observability strategy. Enter: AIOps. AIOps stands for Artificial Intelligence for IT Operations. It combines machine learning, big data, and automation to help teams manage increasingly complex systems. Instead of reacting to every alert manually, AIOps analyzes patterns, correlates signals, and filters out the noise, so engineers only get notified when it truly matters. Why It Matters for On-Call Engineers 🚨 The goal isn’t to replace human ops, but to support them. With AIOps: Redundant alerts are suppressed Anomalies are flagged earlier Root cause analysis gets faster Response times (and stress levels) drop Especially in cloud-native and microservices-heavy environments, AIOps can be a game-changer for keeping teams focused on what matters, not just reacting to noise. We made a short video that gives you a fast overview of what AIOps is, how it works, and why it’s gaining traction in high-scale operations. Great if you're curious but don’t have time for a deep dive (yet). Have you started using AIOps in your stack? I’d love to hear how it’s working for your team, or what challenges you’re still facing.  ( 3 min )

Managing state in a modern web app can get tricky, especially as your app grows. If you’ve ever found yourself passing props down multiple layers of components in your Next.js project, it’s time to meet your new best friend: React Context. In this post, we'll explore how Context works in a Next.js app, when to use it, and how to set it up step by step—with simple examples for beginners. In plain English, Context is a way to share data between components without passing props manually at every level. Think of it like a global store that's accessible to any component in your app, as long as it's wrapped in a Context Provider. Next.js is built on top of React, so it supports the React Context API out of the box. Context becomes useful when: Multiple components need access to the same data (e.…  ( 5 min )

I recently spun up a CentOS Stream 10 Minimal VM in VMware so I could test some networked services. To my surprise, after installation I ran: $ ip link show 1: lo: … ` …and that was it. No eth0, no ens33, nothing but the loopback device. A quick lspci | grep -i eth did show an old AMD PCnet-PCI II adapter, but CentOS wasn’t loading any driver for it—and worse, my bridged LAN had no DHCP server so even a loaded driver wouldn’t help. Here’s a concise “restore-your-VM-network” recipe that worked for me every time. Drop these steps into your personal wiki or a Gist, and you’ll never get stuck without a NIC again 🤓. Inside the VM: bash lspci | grep -i eth shows: No real interface (eg. eth0 / ens*) is ever created. Legacy NIC: VMware’s default PCnet-PCI II (pcnet32) adapter isn’t supported out-of-the-box by CentOS Stream Minimal. No DHCP: With the adapter in Bridged mode on a network lacking DHCP, the interface—once up—couldn’t grab an IP anyway. Power off your VM. Open VM → Settings → Network Adapter. Select NAT instead of Bridged. ✓ Check Connected and Connect at power on. OK, then Power on. NAT mode uses VMware’s vmnet8 network and a built-in DHCP server. You’ll always get a lease. bash Your interface name may vary (ens33, enp0s3, etc.). First, test DHCP manually to confirm VMware↔DHCP communication: bash You should now see something like: bash And: bash To have your VM auto-connect on reboot, use nmcli: `bash sudo nmcli connection delete vm-dhcp || true sudo nmcli connection add \ sudo nmcli connection up vm-dhcp Verify: `bash ip addr show ens32 ` bash If you get replies, congrats 🎉—you’ve restored full networking to your CentOS Stream Minimal VM! Driver-only fix: If you prefer to stick with the PCnet32 adapter, you can instead load its driver: bash But you still need a DHCP server on your bridged network. Bridged with DHCP: If your physical LAN has a DHCP server and you really need bridged mode, switch back to Bridged after loading the driver or switching NIC type to e1000/vmxnet3.  ( 4 min )

Introduction Even though nascent “threads” appeared as early as 1966, they weren’t supported by any major programming language of that era. POSIX threads aka, pthreads (“pea-threads”) didn't appear until 1995. Consequently when C was created in 1972, it didn’t support threads at all until pthreads came along. Pthreads is widely available on any Unix system and even Microsoft Windows ports exist. Among other things, C11 added standard library support for threads. Its API is necessarily superficially different from and a subset of pthreads. While that’s not terrible, it’s unfortunate; more unfortunate is that standard threads are optional for implementations. Specifically, if the compiler predefines the __STDC_NO_THREADS__ macro, then standard threads are not supported. Hence, if you’re…  ( 7 min )

If you run docker build, you need to understand what's happening under the hood. It’s not magic — it's a clever use of containers themselves. Here’s the breakdown 👇 docker build? When Docker builds an image, it reads your Dockerfile line by line. But here’s the key: not every instruction creates a new layer. 1. For instructions that change the filesystem (RUN, COPY, ADD): It spins up a temporary container using the image from the previous step. It runs the command (e.g., RUN apt-get update) or copies the files inside that container. It commits the result as a new image layer that contains only the filesystem changes. 2. For instructions that only change metadata (WORKDIR, ENV, CMD, EXPOSE): No container is created. Docker simply updates the image's metadata (the config.json file) to be …  ( 4 min )

My goal was to build something clean, functional, and easy to extend for future features. Live Demo: [https://office-iq.vercel.app/] Source Code: [https://codesandbox.io/p/sandbox/github/SumitDesai-21/OfficeIQ] This project was a great opportunity to practice building a React app with modern hooks and state management. I focused on: User Experience: The form is simple, with clear fields for title, date/time, description, and attendees. I used a multi-select dropdown for attendees, making it easy to add multiple people to a meeting. State Management: All meetings are managed in local state for simplicity, and the list is sorted by upcoming date/time. Styling: Tailwind CSS made it easy to create a clean, responsive UI with minimal custom CSS. Learning: I learned more about handling multi-select inputs in React, and how to keep forms accessible and user-friendly. What I'm proud of: The app is easy to use and visually appealing. The code is organized and ready for future enhancements, like persistent storage, notifications, or integration with a real user directory. Next steps: Add persistent storage (localStorage or backend) Integrate with a real calendar API Add authentication and user management Improve accessibility and mobile responsiveness Team Submission: Solo project, but open to feedback and collaboration! License: Feel free to use or adapt this project! (MIT License recommended) Thanks for checking out my submission! 🚀  ( 3 min )

My first coding job was not what I expected. I was getting paid to do nothing! Or so I thought. I landed it straight out of college, and at the time, I thought I had hit the jackpot. A full-time coding job after a simple interview process? It felt too good to be true, and in many ways, it was. Orientation started with a group training program. We took classes and had to pass tests on Java, MongoDB, and Splunk - tools I was already familiar with from college. Some of my new coworkers, however, struggled. Curious, I asked around about their backgrounds. To my surprise, most didn't have a programming background at all. That was red flag number one. Still, I continued with the three-month training program and passed everything with flying colors. After training, we learned how the company actu…  ( 6 min )

The recent $44 million hack on CoinDCX hasn’t just blown a hole through the company’s "safest exchange in India" narrative—it’s exposed a darker underbelly of crypto public relations, influencer manipulation, and opportunistic hypocrisy. For those who’ve watched CoinDCX operate over the past few years, the breach wasn’t just a security failure. It was karma. When WazirX suffered a major cyberattack exactly 1 year ago on July 18, 2024, it responded with regular user updates, affidavits in court, law enforcement cooperation, and a visible roadmap for recovery. But instead of showing industry solidarity, CoinDCX seized the moment to push WazirX down. A coordinated influencer campaign followed—funded and promoted through CoinDCX’s PR channels. Influencers were paid to post hit pieces, amplify …  ( 4 min )

In 2017, I started working with Angular 4 as my first frontend framework, altough I was a PHP backend dev who had pretty nice experience with CSS, HTML and bootstrap. I totally dedicated myself to build the project I was given to me from scratch while I had zero experience working with Angular and the deadline wasn't very long. However, In the end, the result was spectacular, the company was so satisfied and I learned Angular from scratch in a very short time working on a real project. I fell in love with Angular and did serveral projects with it afterward for years. Recently, I had some very good job opportunities that required React.js and I decided to learn it, although because of Angular's beautiful structure, all of my previous efforts to get started with React had failed before.

A coffee table might seem like a small piece of furniture, but in reality, it’s the unsung hero of your living room. It anchors the space, invites conversation, and adds both function and personality. Whether you're sipping evening tea, hosting friends, or just resting your feet after a long day, the right coffee table makes all the difference. Before you browse styles or colors, evaluate the size and shape of your living room. A living room coffee table should complement your sofa and layout, not overwhelm or disappear in the space. There are plenty of materials out there, from glass and metal to MDF and engineered wood. But nothing matches the warmth, strength, and timeless charm of solid wood.

React Query is a powerful state management library designed for handling data fetching, caching, and updating, particularly suited for API interactions. It offers advanced features such as automatic caching, offline state management, data expiration, and refetching. npm install react-query In your application, you need to import the useQuery Hook and set up a configuration object. import { useQuery } from 'react-query'; const queryClient = new QueryClient(); Wrap the queryClient around your root component using QueryClientProvider to make it available throughout the application. import { QueryClient, QueryClientProvider } from 'react-query'; const queryClient = new QueryClient(); function App() { return ( {/* Your application */} …  ( 6 min )

I used to lie awake at night thinking about my code. Was that function elegant enough? Could I refactor that module one more time? Should I rebuild the entire architecture with the latest framework? For a long time, I was trapped in perfectionism, something that so many developers today struggle with. We’ve been conditioned to believe that our code needs to be flawless, with zero bugs, clean architecture, and the newest technology stack. It’s a dangerous belief that can weaken progress and kill innovation. The truth hit me during a particularly intense code review session. A senior architect, someone whose work I deeply respected, made a confession that changed everything. He said, “I’ve never written perfect code. Neither has anyone else in this room. That’s exactly why we’re successful.”…  ( 6 min )

As developers, we all want our workflows to be smooth and efficient. Managing repositories, reviewing pull requests, and keeping track of changes can get tedious—especially when it means switching between your editor and browser. Recently, I set up the Bitbucket MCP (Model Context Protocol) server with Cursor IDE, and it’s made these tasks much more convenient. While Cursor supports bugbot for GitHub PR reviews, there’s nothing similar out-of-the-box for bitbucket users. Setting up Bitbucket MCP with Cursor changed that for me—and made my dev life a lot smoother. Here’s a practical guide based on my experience, with tips that apply even if you use other tools. The main benefit is reducing context switching. With Bitbucket MCP, you can: List and manage repositories Create, review, and appr…  ( 7 min )

In my backend projects, I got tired of constantly writing raw status code numbers like: res.status(200) res.status(404) It works — but it's not expressive. And honestly, it makes code harder to read and maintain over time. Like many developers, I wanted something cleaner, more intuitive, and easier to understand at a glance. So I looked into existing solutions. http-status-codes http-status-codes is a well-known package. With it, you can write: import { StatusCodes } from "http-status-codes"; res.status(StatusCodes.OK); Much better than hardcoded numbers — but it came with a few drawbacks: ❌ No ESM support ❌ No localization ❌ No detailed reason phrases ❌ Separate type definitions (@types/http-status-codes) ❌ Slightly bloated — 12+ KB minified It didn’t quite solve my problems.

Hey everyone 👋 If you're getting started with cloud infrastructure or learning Infrastructure as Code (IaC), one of the first tools you’ll hear about is Terraform by HashiCorp. It lets you define your infrastructure using simple, human-readable config files — and then deploy that infrastructure automatically across AWS, Azure, GCP, and more. But before you can build anything, you need to install Terraform. Let me walk you through how to do it the fast, easy way 👇 Terraform is a command-line tool that helps you provision, change, and manage infrastructure across multiple providers. It’s lightweight, fast, and once installed, gives you a powerful CLI to define your infrastructure as code. There are two main methods to install Terraform: ✅ Using a package manager (recommended) 🛠️ Manual do…  ( 4 min )

JavaScript has evolved massively since ES6 dropped in 2015. Are you still writing JavaScript like it’s 2010? You’re making your life harder than it needs to be. These features actually solve the annoying problems you deal with every day. React, Vue, Angular — they all lean heavily on ES6+ features. You can’t really avoid learning them anymore. Plus, they help you write less code, introduce fewer bugs, and actually maintain your projects without frustration kicking in. let and const are new ways to declare variables that were introduced in ES6 to replace var. They provide better scoping rules and help prevent common JavaScript. The old var keyword creates confusing behavior. Variables declared with var are function-scoped and get “hoisted,” which leads to unexpected results. Here’s how you…  ( 5 min )

Problem Have you faced a situation where a lot of messages went to the dead-letter queue in azure service bus and then you need to clean it? You can easily go to azure portal and peek at messages and clear them. But if you have more than 20k messages, maybe it becomes painful to select one by one and clear. Other than that, it is important to understand why messages went there for troubleshooting reasons and help you to fix any issue that your application may be experiencing. What to do in such a situation ? A high number of messages in the dead-letter queue is a clear indication that your application is not able to consume them and usually they go there after the max attempts are reached.
